BJ,
Are you talking POT of >100%? If you are and you genuinely can do that over a long period, then you would be the most successful punter I have ever heard of. Good luck to you. I am very happy with a POT of around 12%.

How on earth do people do form without watching race replays? Whether it be dogs, trots, thoroughbreds, tennis, NRL, AFL etc etc., if you don't see them how do assess their ability and style?
