Also, I believe I've read somewhere here from you TGJB that you could make even more precise figures if you had the horses weights to go by - I believe regarding the weight carried adjustments? Would you mind explaining how you would use that info to make even better weight adjustment? In theory. Certainly something about the relative weight carried, but not quite sure about the details about how you would go about incorporating it into your figures.

My guess is that for US racing it's probably not worth the trouble, anyway, but for racing in countries with frequent handicap races and big weight discrepancies it is an interesting idea.
