thanks.

I have been doing something of this already, but in a haphazard way. I haven't considered class enough, though. I just tend to avoid races where too many horses have too few career races to give meaningful stats.

What about the problem of easy race = poor dividends. Should I be looking for the easy races? OK, if I'm using a system that backs favourites, but there's no value for money in it.

Does anyone deliberately seek out races that are hard to pick on the theory they'll pay better if you do get a winner? To what extent should one look at the money anyway?
