You could cut that list pretty much in half as you are doubling up on information that is already in the database.

For instance records like, WETRACES, WETWINS, WETSECS, WETTHIRDS, TRACKRACES, TRACKWINS, TRACKSECS, TRACKTHIRDS dont need to be entered in each time you write to the databse as have already been entered in the databse previously and you can query the databse to get those results should you so desire.

What i mean by that is there is no need for a specific field say WETWINS because if you want to find out how many times a horse has one in the wet you would query the database.

Anyway, if you are serious, wesmip has given a pretty comprehensive list of the sorts of things you might want to keep records on, other than that start reading
