Hey Rod,
From it's inception in 1983, CCS's standard sprint length was 16 miles. (4 laps at Road America)
Sprints at Road America used to be 5 laps, Unlimited GP 8 laps and the Solos usually went 12-14 laps depending how fast you were/are.
Late eighties to early Nineties the turn out at Road America was 470-550 entries, and now it is 1700-2000.
With the track length at 4 miles, even a conservative track density is 100 machines, (considering the widest front straight in the business and the distance from the grid to turn one, that number is very conservative) and since 1999 we have never allowed more that 100 bikes on the course at one time, even in practice where you can safely allow 125% of track density. The biggest grid to start this year was 89 machines, with 6 no shows. The only class that possibly could have started more than that was the Unlimited SuperSport Combined which would have been 112 machines, BUT we split that race along with one other so we ended up with 18 races on Saturday instead of the 16 that were scheduled.
With our new classes, we are only adding one race to the weekend, AM UL GP, the other classes will run in conjunction with races already on the track, like the GP Single / SuperSingle / Ultra-Lightweight Sportsman combination. By 1988, CCS already had 30 classes, and that number has fluctuated up and down over the last few years, but now it is set at 40 and is likely to remain there for the foreseeable future. (WERA offers 49 classes at it's races, so I am not sure where you get that we are only interested in the "CCS cash cow".)
Oh, and thats two "L's" and two "T's" in Elliott. ;D
Good Day.
