Hmmm, those figures might be a bit bendy for using to make assumptions [Caulfield is easier to bet on] beyond the obvious facts of win/loss % there ....for those that bet Cauilfield anyway.

I'm sure a lot more mug money [a huge amount more] gets spent at Flemington, especially during the spring and Melb. Cup carnival, that ever gets spent at Caulield, which would 'load' the loss figures at Flemington. A lot of average punters avoid betting on Caulfield because of it's difficult reputation, but it also draws a lot of specialists which perhaps loads it's win figures and lightens it's loss figure [?].

It might be drawing a long bow to jump to conclusions about punting difficulty or anything else from basic track win/loss figures at any track. Do you see my point ?
