I agree with Arch and Joe except the part about adding a class. I think we have enough to handle from a contest management standpoint. Make Sportsman (or whatever it may be called) a non turnaround event that can be flown with any sport plane. Then have Intermediate the first turnaround event with a schedule that suits the skill a pilot would have when they move out of Sportsman - perhaps a box exit in the middle of the routine to get back on track.
