Thanks, Koidog, you didn't jinx me! Very good day yesterday. Had the winner in all 10 races. To put in perspective how difficult it is to make money doing this, if you wagered the minimum $2 to win on each of my picks ($60 investment) your profit was $43.40 - and that was winning every race! I also managed to hit 6 of 10 exactas. With a minimum $1 box on every race (again $60 investment), the profit was $131.90.
Now, we're looking at just over $175 profit on the absolute minimum bets, right? Well, I just checked my account summary and with all bets across all tracks - I played GP, CD, and Belmont yesterday - I wagered $468 and cashed $464 for a net loss of $4.
It goes to show you it is as much about money management as it is about picking winners. Good times.
