It has been suggested by some on this forum that the S.P market has been the most accurate as far as results are concerned, How would it compare with the pre post market? would there be much difference?
Also what percentage of longer priced winners say 10S or longer would have been shorter in the prepost and drifted compared to the ones that were longer in the prepost?
I think that more would have shorter but would be interested to know on a large sample.
