Jock Mount fees - Horseman office question?

There is a list of fees that the jockeys recieve in the back of every condition book. From there you can use the charts and figure out what each makes in any race. We used to do it that way to keep track of what we had coming as agents. The only caveat to that is sometimes a jockey will charge 10% if he or she finishes 2 to 5th in a stakes race. Since that fee is not covered through the paymaster his agent will invoice the owner.
