Think that may depend on what you are filtering,ratings for example i am 100% convinced that the "BEST" filters are race filters,not these horse filters.

Of horse filters i would have to include no spell (90day) in last three starts,it gets right to the fitness issue and takes the uncertainty out of it,a horse could have raced within the last 14 days but that on its own doesnt mean its fit,it could be returnin g to fitness,its a very different thing.

I also love to filter to race starts,fresh reliable legs who have yet to hit their career peak,cant go past a 19 race starts or less filter.
