I was referring to trying to litigate "fun" not just the number of races.

There are several exceptions listed in this thread as to how many races to run per day, depending on the wind, cold, rain, day of the week, weather on the remaining days, etc.

Do we state in the SIs to run 4-5 if it is warm and sunny, fewer if not?

Again, I agree that something in writing could help. But, the experience of the PRO should help even more here. If there are examples where this isn't happening, there's only so much you can do with an NOR. The real answer seems to be to work with the PRO, or make a change in that position.
