Becareful, you indicated that Hermes idea would produce an overall loss on Sat metro races.

Do you have any 'feel' for the situation if all races were considered? Don't want you to run your whole database or anything, but your obvious work on your punting would, I think, enable you to give an educated guess.

Personally, I 'feel' that there may be a lot more value in many weekday and out-of-town races than most of us suspect. Maybe Hermes' filters, if we can call them that, would help?
