Here is a couple of Questions that have intriqued me since the days of Barry Blakemore.

1/Do Fillies/ Mares have a advantage over Colts /Geldings.

2/ Is there a cutoff point between days since last run.

3 / Do favs have a advantage over non Favs .

4/ Do 2 +3 YO have any advantage over older horses.

The questions are specific to 1st Up .
