I agree John - rolling around the track by yourself is a driver ed day, not a race. It's not always about where you finish but the excitement of passing and being passed and working on race craft. Running door to door with other cars in all classes is where it's at, at least, that's what I like and it's missing at SP for ITR. Lot's of the tracks in the NE have S and R battling to the finish and I don't know anybody complaining about messing up class specific races.
But I don't think this will be a problem because ITR will skip SP and go to NJMP.
I do respect that the guys getting lapped lose some track time. When I ran GT1 at LimeRock the friggin race lasted 15 minutes because we ran in the low 50's for a 15 or 18 lap race. Anybody grouped with GT1 was pretty unhappy - nobody wants a shorter race.
