Its all to do with probability and some more advanced topics on it. I beleive using the analysis I do is the correct way to know when to bet a system.

The answer to your last thing is if you do have an edge the more bets you have the lower the % chance plays a role. So you would normally see a system sit at 100% chance to start with and slowly move away to be pure edge. As I said half a percent chance is the right time to start betting. before that you should collect more data.

Hope that helps. If you ever want a system analysed make sure you keep your stats for me (every odd on every horse win or lose).
