Well after doing the numbers based on my results from last week, I get a better return if I do 10 E/W. Even better still if I just do 20 for WIN and don't place bet. Tho more results the better, so won't really have a better idea on which way to go for a few weeks yet. Like for instance, at moonee value I got 4 winners (placing 1st) in a row. So that makes a big differance to the end of week profit/loss value. I want to wait to see when I don't have such success how my strategy stacks up.

Still I'm confident I'm onto something with my strategy as I picked only one race yesterday and the horse placed 1st. Looking at my results so far, when a horse does place for me more often than not it is 1st place (instead of 2nd or 3rd).
