You make a logical point there Party.

The figures in the book where just raw figures without anything else like No. of starts.

I feel it gives a strong starting point to frame certain filters, so there is definitely room for improvement .

One observation of mine is horses which have a max of 69% Place rate, seem to perform more consistently than horses greater than this mark, for win betting.

Probable because of the reasons you have outlined.

This could be kept in mind when trying to separate say 2-3 horses.

Cheers.
