I apparently have considerable experience from the rear of the field in 600prod. No lapping occurred at my only monowave T'hill race, at Infineon the top 10% catch or lap the bottom 15% as is. With 2 more laps at T'Hill, I'm guessing the top 40% would catch/lap the bottom 40%. Maybe in a multiclass grid, you could get riders passed twice by the leaders, I didn't do the math there. I don't know when or if that is a problem.
