Thanks for the replies, Mark and Chrome. Appreciated.

Chrome, while your figures are instructive (to say the least), does what happens to favourites tell the complete story? While there is usually only the one favourite, there can be several non-favs second up in any given race.

Just wondering about the logic here. I have been working on a little system which has done very well on the country and provincial tracks; but has done miserably on the metrop. tracks. I understand all about small samples, etc., etc.; but am wondering if the results for favourites are 'skewed' on the metrop tracks. The available prizemoney, for example, must have an influence one would think, and the quality of the starters too.

Again, my thanks.
