Tested over 34,000 horses

0-7% (1st uppers)

4-11%
5-10%
6-10%

8-11%
9-9%
10-7%

It shows that the horses 4-9th up after a spell, have fitness on their side.
Therefore have a stronger chance of winning.

10th onwards & the stats start falling away again.

If you would like to get a clearer picture , I could run the same stats over the 1st & 2nd paper Fav to give you a different perspective.
Let me know.
