Sports betting lost -1,388€ today. 3 games today, all 3 lost for me. The first game that is shown as a winner is Den Haag vs Groningen which was not settled until today.

Sports betting won+243€ today. Only 6 games to bet on and almost got a grand, but Manchester scored late in the game unfortunately. There are also few games tomorrow so I don't expect any big wins or losses.

My strategy in sports betting is based on an Excel spreadsheet. I add the games in daily basis and I update the results during the day...

In that way, the spreadsheet keeps tracking of my performance, adjusts my bankroll and calculates my stake size for each game. According to some filters I have applied, the spreadsheet tells me what to back and what to lay and for how much.

I have created my sheet in that way, so I can keep track of my performance, whether I would flat bet, or in case I used the Kelly criterion. Since December, I bet according to the latter, although I started with flat betting, since I wanted to be sure it was a winning strategy.

Up to now (late April 2007), I have placed bets on about 5,000 football games while my database consists of about 6,500 games. Here are some interesting stats:.

Flat Betting Performance

Sports betting lost -2,088€ today. Although I still expect some good days, that loss was not a surprise after all, since the profits were more than adequate the previous days. We will see what the champions league brings tomorrow.

The past week was a very good week showing some very nice profits. The week started rather slow and really picked up during the weekend. This uphill was somewhat expected according to my strategy statistics, so I couldn't be more pleased.
