Am I right with the following?
Assuming an 8 race programme then you would need a favourite to win in the first 4 races for the plan to be followed. If the fifth race was the first one where the favourite won then there would only be 3 races left in the day which would not provide you with your max number of outs.

I must admit I don't see how this method can work in the long run since I can't work out why betting within a meeting gives you an advantage. I am sure if you simply follow the races in a day and simply bet on the favourite after the first favourite has won during a day then in the end you would lose....so why would it work for a single meeting?
