MR3,
there was a "late go" for a certain runner which eventually won.
I was on No.7 the usurped PP favourite which ran 2nd and paid $1.4plNSW which equals a 16.67%POT so I am not "talking through my kick!"
No.7 missed the start and settled well back in the field and unleashed a solid run in the straight but the winner had too big a break.
However, I again ask the question: "how is it that the favourite or well-fancied runner misses the start on a disproportional ratio of racestarts?"
You will have to ponder this and work it out for yourselves.

Cheers.
