Hi Gunny, no idea about the data base.

Fitness is a hard thing to judge, quite a few people will tell you the horse must have raced in the last 21 to 28 days or something like that but unless they can give you the percentage of winners to runners either side of X amount of days all they are really saying is that the large majority of horses have raced within that time frame so of course most of the winners will have raced in that same time frame.

Personally i'd stick to horses that have won one of their last 3 starts this side of a spell,surprisingly a lot of decent priced winners have that requirment and at least you know you are backing in form fit horses.
