SprotsBetting Champ; Update: Aug 18, 2008

OK, so apparently John Morrison has made a tweak to the system that takes into account a statistic called “Relative Power index”, or “RPI”, which takes in to account the team’s winning percentage and quality of opponents. The new tweak would pass on “qualified” picks who have an RPI that is less than a certain threshold. Apparent back-testing would have eliminated virtually all losses in the last 20 years and 27% fewer games/series to bet on. The current season would apparently be 37-0 using the new tweak, and all future picks this season (and beyond0 will be made with the new tweak, apparently. In addition, all 37 wins this season would have occurred on the “A” or “B” bet, and virtually eliminated the “C” bet.

I will await further testing, but I am leaning towards recommending this system, but with caution. With only a few games left to bet on this season, I will probably bet on it next season too, as the new tweaks seem to make it better, though time will only tell.

Within the next couple of days I will update what the results would have been for this season with the new tweaks, though they will not reflect my current results.

FTWF; Update: Aug 18, 2008

Sorry I have not updated this blog in a few days; I have been away attending my brother’s wedding out in Ontario.

While I was away, the English and Scottish Premier leagues started up, and I had pre-bet two games on it using the “Four The Win Football” system:

• Aug 16: Rangers vs Hearts
• Aug 17: ManU vs Newcastle

The Rangers won while ManU tied. Since i am flat-betting, I will not be increasing my bet size on the next game, which will be Porto FC vs Belenenses on Aug 24th.

Results for the weekend are:

Aug 16, 2008
Start Bank/Bet Amount: $125.00 / $25.00
Result/Odds: Win / 1.38
Profit/Loss: +$9.50
End Bank: $134.50

Aug 17, 2008
Start Bank/Bet Amount: $109.50 / $25.00
Result/Odds: Win / 1.38
Profit/Loss: -$25.00
End Bank: $109.50

Just as a reminder, I am going to flat bet the season, not increasing my bets, to give a more true test of the system. I will also be tracking results using two other betting systems, but they will be theoretical, and not actually bet. I may make my spreadsheet available periodically to show the results.

Update: Sports Betting Champ, Aug 8, 2008

It’s been a while since my last update on this… July 23rd, in fact. The system is currently in the middle of two series (there were two picks today, both of which lost the first game of their respective series, so there will be a second bet on them tomorrow). Current status for completed series is:

From: Jun 9, 2008 to Aug 5, 2008
Number of Qualifying Picks: 35
Number of Wins: 31
Strike %: 89%
Total Amount bet: $1,260.90
Total Profit: ($144.06)
ROI: (11.43%)

Will update once current series are done.

European Football System: FTWF, part 2

OK, in all future posts, I will refer to this particular Football system as “FTWF”, which is short for “Four The Win Football”.

As promised, I have done some “Risk of Ruin” calculations to determine what a good bankroll size would be to do this system with. As you may recall from my previous post on this subject, I initially did some calculations using 20% of the bank as my betting unit, but felt that without further data, it might be safer to use 10% of the bank as the betting unit.

To do the calculations, I used the the “Bankroll” calculator at this site. While the site is really for calculating a poker bankroll, it is still applicable here.

Using my spreadsheet, here are the results:

Flat Betting
Betting Unit: $25
Average Profit per Game: $3.96
Standard Deviation of the profit (using the “STDEV” function of the spreadsheet): 13.71

Plugging the numbers into the “Bankroll” calculator like this:

Win Rate: 3.93 (this is is average profit per game)
Standard Deviation: 13.71 (the standard deviation of the profit/loss)
Risk of Ruin %: (see below)

Using a “Risk of Ruin %” of 5 resulted a a bankroll requirement of only $71.64; “risk of Ruin %” of 1 resulted a bankroll requirement of $110.13

1-2-3-1 Staking Plan
Betting Unit: $25
Average Profit per Game: $4.62
Standard Deviation of the profit (using the “STDEV” function of the spreadsheet): 16.05

Plugging the numbers into the “Bankroll” calculator like this:

Win Rate: 4.62 (this is is average profit per game)
Standard Deviation: 16.05 (the standard deviation of the profit/loss)
Risk of Ruin %: (see below)

Using a “Risk of Ruin %” of 5 resulted a a bankroll requirement of only $85.32; “risk of Ruin %” of 1 resulted a bankroll requirement of $128.39

Increasing Betting Unit Based on 10% of Total Bankroll
This one was a little more tricky, since I needed to start with *some* bankroll number as a basis for the calculation. To arrive a betting unit of $25, I needed to assume a bank of $250. Here are the results:

Betting Unit: $25
Average Profit per Game: $4.70
Standard Deviation of the profit (using the “STDEV” function of the spreadsheet): 22.80

Plugging the numbers into the “Bankroll” calculator like this:

Win Rate: 4.70 (this is is average profit per game)
Standard Deviation: 22.80 (the standard deviation of the profit/loss)
Risk of Ruin %: (see below)

Using a “Risk of Ruin %” of 5 resulted a a bankroll requirement of only $165.67; “risk of Ruin %” of 1 resulted a bankroll requirement of $254.68

Interestingly, if I only wanted a 1% “Risk of Ruin”, then my “assumption” of using a starting bank of $250 for this one was actually very close. Actually, looking at all the results, my initial instinct of being able to use 20% of your bank as a betting unit seems to be a good one, but I am still going to use 10% of my bank as my betting unit until i get further data (two or three more seasons)

A couple final calculations:

1-2-3-1 Staking Plan: Each Team Bet At Its Own Series”
Betting Unit: $25
Average Profit per Game: $6.90
Standard Deviation of the profit (using the “STDEV” function of the spreadsheet): 23.42

Plugging the numbers into the “Bankroll” calculator like this:

Win Rate: 6.90 (this is is average profit per game)
Standard Deviation: 23.41 (the standard deviation of the profit/loss)
Risk of Ruin %: (see below)

Using a “Risk of Ruin %” of 5 resulted a a bankroll requirement of only $118.97; “risk of Ruin %” of 1 resulted a bankroll requirement of $182.88

Flat Bet: Each Team Bet As It’s Own Series
Betting Unit: $25
Average Profit per Game: 5.31
Standard Deviation of the profit (using the “STDEV” function of the spreadsheet): 18.97

Plugging the numbers into the “Bankroll” calculator like this:

Win Rate: 5.31 (this is is average profit per game)
Standard Deviation: 18.97 (the standard deviation of the profit/loss)
Risk of Ruin %: (see below)

Using a “Risk of Ruin %” of 5 resulted a a bankroll requirement of only $101.51; “risk of Ruin %” of 1 resulted a bankroll requirement of $156.05

So there you have it; pick which betting strategy you want to adopt, and size your bankroll appropriately.

One final question you might have is what is more appropriate: 5% Risk of Ruin or 1% (or even lower??) That is really up to you. If you are doing this as a hobby or secondary income, then you are probably safe with using the 5% figure, but if you are doing it for a living or just don’t want to go broke, then 1% (or lower) would be more appropriate.

I hope this helps you. As always, if you have any comments on this article or the numbers used in it, please feel free to comment.

European Football (aka “Soccer”) System

Wow, two posts in one day

I was surfing around for some good Betfair betting/trading systems, and have found some good ones, which I will cover in some future posts, but wanted to share my thoughts on a Football system that I came across at the Four The Win Football site. It’s a free system (well, it’s not really a system, as you will see), though they have a couple other systems, notably horse racing, that they sell (and which have had really good reviews, but are beyond the scope of this post)

Anyway, since it is free, I will share the “system” here with you.

It involves betting on the top-tier teams in European Football who had the best home records (no more than three, maybe four, non-winning results the previous season; so in other words, no more than 3 or 4 draws or losses) You then bet on those teams the following season when they play at home.

Note: The results posted on the website report in “Great British Pounds”, but since I do not have the symbol for “GBP”, I am going to use exactly the same numbers, but use “$” instead, as I do not believe that changing the monetary symbol actually changes anything.

They posted their results for the previous season, which results in about $21,160 over the course of the 10-month season (Aug-May), betting $1,000 each game. They recommend the following “staking” pan: 1-2-3-1, meaning that you bet one unit, if you lose, your next bet is two units, then three if that one loses, and if there’s a 3rd loss, you just cut your losses and go back to one unit.

I put their results into a spreadsheet and played around with things a little bit (trying different betting strategies and the like). Here are some interesting things I found:

1. I played around with the best size of bet to bankroll ratio, and while I found that making your “one unit” bet 20% of your bankroll worked, until further data is available, I would probably be more comfortable with using 10% of your bankroll as your “one unit”. I will probably do a “risk of Ruin” calculation and see what the best bet size/bankroll is based on that, and post an update to this in the very near future.
2. Their results are missing four final games for the teams they bet on. I do not know if the omissions were on purpose, accidental, or if they just simply did not bet on those games. Adding in those “missing” results changes their overall profit from $21,160 to $19,880, which is still quite a hefty profit, although adding in those “missing” results actually resulted in an overall loss on one of the teams. Note that since I did not have the odds for those four “missing” results, I averaged out the odds from all the others games which I used in my calculations for those “missing” games (the average odds worked out to 1.36)
3. The results they post list how much money was made on each team, so they seem to treat the 1-2-3-1 staking plan on a per-team basis. Betting per-team, out of the 95 bets, it was necessary to go to the “2″ bet 11 times and the “3″ bet once.
4. Playing with things a bit, I had a look to see what would happen if, instead, you mixed everything up and just bet on each team as their games came up on the schedule, and did the 1-2-3-1 staking plan that way. The results were quite a bit different:

   a.) $17,560 profit (a difference of -$2,320, using the “adjusted” figure of $19,880 above). While a bit less, it’s still a pretty healthy profit considering the “blue chip” teams your are “investing” in
   b.) Out of the 95 bets, it was necessary to go to the “2″ bet 12 times and the “3″ bet twice. Actually, one of the “3-bets” were the last three games of the season, and the last game “won”, though even it had lost, the profit on the season would still would have been a respectable $13,480

5. I played around with one other betting strategy which involved having your base bet as 10% of your overall bank but staying at that level until your bank reached certain “milestones”. For example, starting with a $150 bank, you would bet $15 (using the 1-2-3-1 staking plan) until your bank reached $200, then it you would start betting $20 until you reach $250, then you would bet $25 and so on. The “milestone” amounts were set at $150, $200, $250, $500, $750, $1,000, $1250, $1500, 1750, $2000, $2500, $5000, and ending at $10000. Using the above results, starting with a $150 bank and $15 base bet, and betting on each team as their games came up in the schedule would have resulted in a profit of $446.80 with the base bet increasing to $50.
6. Finally, as a true test of the system, I tested to see how it would have done by flat-betting, which of course tells us truly whether or not a system is profitable. I tested flat-betting using a $10,000 bank and $1,000 as the “base” bet (i.e., treating each team as it’s own “series”, and mixing them all together) so the results are easy to compare to theirs. This resulted in the following:

   a.) Each team as its own “series”: +$15,050
   b.) All teams mixed: +$14,150

All in all, it would appear that if you were not planning on increasing your “base” bet size as your bank increases in size during the season, then betting each team as it’s own “series” would likely yield the best result, but no matter what method of betting you decide on, you would have been looking at similar results.

I will post an update in the very near future with the results of a “Risk of Ruin” calculation, including how I derived at the answer in case anyone has any further insights. In addition, I plan on using this system on the upcoming season, then the increasing stakes through the season as my bank increases. I will post the results (good and bad) as it progresses.

Sports Betting Champ Update: Jul 23, 2008

I haven’t posted in a couple of days, so I thought i would put something up. I am currently in the middle of a series, and going into the third game of it, so hopefully the “pick” will win tomorrow’s game (Jul 24)

I was just looking over the SportsBetting Champ site, and he seems to think there has only been three “losses” this season, as of Jul 23, 2008 (remember, a “loss” in this system is when the system pick gets swept in the series). I am almost certain that there has been four, possibly five. When he sends out his final tally (usually at the end of the season), I will have to compare that to my own notes and see. I will also then be able to play around with the results in a spreadsheet and try different betting strategies.

I will post more tomorrow when I know the final results of this particular “system” pick.

Sports Betting Champ Update #2: Jul 21, 2008

OK, so the three picks went 3 for 3 (BAL vs TOR, DET vs KC, and ARI vs CHC)

This brings my results to the following:

Number of Qualifying Picks: 18
Number of Wins: 16
Total Amount Bet: $ 547.11
Total Profit/Loss: -$115.84 (-21.17%)

Sports Betting Champ Update: Jul 21, 2008

OK, so the 15th qualifying series I was betting on resulted in a sweep against the system pick (the series was San Francisco vs Milwaukee, if it is of interest)

So, current results for the system, since Jun 27, 2008, are as follows:

Number of Qualifying Picks: 15
Number of Wins: 13
Total Amount Bet: $ 502.71
Total Profit/Loss: -$145.84 (Loss)

Betting System Review: Sports Betting Champ

I have seen many web reviews of the sports betting system “Sports Betting Champ”, available at. The system claims a very impressive 97% strike rate on baseball and basketball, and he has his statistics from the previous four years to show that. After purchasing the system, you also get sent the picks via email so that, while you know how to derive the picks, you don’t actually have to do the legwork yourself.

I went ahead and spent the $197 for this system to check it out. The system is based on betting on a team winning at leas one game of a three game series, but there are very specific factors for a series to qualify. The betting is a progression-based system, where if you lose the first bet of the series, your next bet is designed to win all your previous money back, plus your original profit.

The problem with this type of betting is that your profits can easily be wiped out by one loss (in this case a series sweep), which will happen about 3% of the time (i.e., the team you are betting on will lose the series to a sweep)

I have been using this system since June 27. My actual results during this period have actually results in a small loss, but I have come to realize that it is due to my betting method, which I have since adjusted. Also, since I have been using the system, there has been one “loss”, though there has been a total of three for the entire season (i.e., the team being bet on was swept)

Since June 27, there have been 15 qualifying bets bets, one of which is currently in progress. Of the 14 “completed” ones (which include the three “loses”) I have bet a total $371.71, resulting (thus far) in a loss of $14.84. The current betting series on on the third game of the series, so if I win, I will only be down $4.84.

Now, I had mentioned earlier that this had to do with my betting strategy. What I originally started out doing was betting a maximum amount of $10 as my first bet, and accepting whatever the return is from the odds given. I have since back tested my results, but aiming for a $10 profit and making the bet amount be determined by the odds offered. From those 14 “complete” bets, and even taking into account the three “losses”, I would have bet a total of $342.67 resulting in a profit of $28.18. So that is how I have been betting since I figured that out.

All in all, I would class this betting system as “neutral”, since it does appear to be profitable but has the potential to wipe out massive profits with one “loss”. I will keep everyone updated on the progress with this system.

Please feel free to share any thoughts you may have, or your own experiences with it.

Movie Review: The Dark Knight

OK, so I saw The Dark Knight tonight and and what can I say? It was better than Batman Begins (though I still loved that movie). heath’s Joker was very dark and disturbing, which was an interesting contrast to Jack Nicholson’s Joker. I can understand why the role haunted Heath ledger (by many accounts)

There are some nasty surprises, which I will not spoil here, but suffice it to say that you’ll be shocked more than once.

All in all, 5 out of 5 stars!
