When Maths Lie!
Sports Betting - Betting Performance
Saturday, 01 September 2007 01:39

Once upon a time I trusted mathematics. I really did. Nowadays I am full of doubts. I had heard of stories where the betting strategy failed to perform in the same way and started a big losing run forcing the bettor to quit it. I kept wondering how that was ever possible. I don't any more. Here's why:

 

Sports Betting pertformed really bad lately (Excel graph)

 

I started my betting system as you know last September. I recorded the bets and my stats for 2 months, made some tweaks, applied some filters and criteria and voila, I had a most promising method. Then I started funding it and saw my P&L climb. That was nice, an additional source of income which didn't need any major effort, just to update the database. Still I didn't have the time so I gave it to my father who had just retired and had plenty of free time. He soon became a huge fan of this new development and carried his laptop wherever he was and betting 24 hours a day! He never missed a game even during the night, wagering on some Mexican and South American games! I was checking my balance in Betfair in the morning only to see some big winnings on some totally unknown for me teams! The bets were made according to the plan, if the data was there then a bet was on its way. Things were getting well, not thrilling but it was a healthy profit.

 

Then came the summer...

July and August lost me 75% of my Betfair funds. I am talking of an enormous bad streak as you can notice from the graph. It is now a week I abandoned the method. It really doesn't make sense. 8,000 submitted bets on a steady uptrend only to be lost in a matter of 500 games.

 

What is left now to do? Search for another method? For what, collecting data for 10,000 games and then lose it all again? How many games are needed in order to be safe? Answer, infinite. I have read in numerrous forums that 1,000 games are necessary in order to be sure of your method. Well, I am here to tell you that even 8,000 aren't enough! Try collecting data and statistics for half of that and let me know if you can continue doing it. It is really VERY time consuming and life sucking procedure. You have to update the scores, record the EXACT odds at the exact time, having many games starting at the same time and at the same time placing the bets! Yes, I know of ways to have your excel workbook update itself by online sites and databases. I can't argue on that, I am just devastated by the whole result.

 

I'm now heavily into poker and hope for the best. Sports trading is still in my plan but things have gone really tough this year, even when using commercial software. There is still money to be made but in my opinion there are other fields where you can be a lot more profitable. That may be foreign exchange (currency trading), stock market (I've started trading in August there), other sports trading (many people trade in-play cricket, tennis and football, I'm not one of them), poker (there are ordinary people out there making over 1 million per year) and so many others. Horse racing's trading just has a lot of tough competition these days.

 

So, best of luck on whatever you are into, and I'll keep you informed of my performances. Yet, I think that it would be better to post useful and informative posts on any kind of gambling, and that is probably what I'll do in the future along with my usual articles. Keep in touch.
