Nice, but too small a statistical sample. The next 200 could easily give you only 29 winners instead of 58 and return a significant loss.
It's like looking for that pot of gold at the end of the rainbow - a winning betting method that requires no effort or time.
It's also just about impossible long term placing bets on the tote in the morning and collecting long term profits in the evening.
I should know. I tried it for years. I finally realised you only get out what you put in. The only way to win at racing is to put in the hard hours, week in, week out and then bet in a disciplined and unemotional manner.
