The above is a total of 6011 races or 13.75% of races where the Fav is less than even money. 1st and 2nd getting between 60% and 90% of wins.

My data base which was given to me, can filter out track conditions weather, distance,and field size. All relate to the fav and the fav's odds and the finishing order based on fav ranking. Unfortunately I cannot sort or filter by race type or quality as they were not in the original criteria.

This is definately a filter at = or <$1.50
