Probably need more information to make an informed comment - in particular what was the actual turnover? You mention half unit bets but you don't say whether you are placing 1 bet/day, 10 bets/day or 1000 bets/day. Also how consistant was the winning pattern? Did it give lots of winners or was all the profit made from just a few big wins? If it is making consistant small wins then I would be a lot more confident than a few really big wins - much harder to tell if the system is working or is just being lucky if you are relying on big wins to make a profit.

Certainly $20,000 in a year is a good return but without knowing the amount invested, etc, I can't say much more than that.
