Your second gripe:
It depends on the level of racing. In classes like 19t, there often isn't enough participation for there to be seperate levels. I think going up is okay, but you can't go down (no sandbagging). RC is about fun, and should include as many people as reasonable. Now iff there was Novice and Intermediate 19t, and that person had done novice stock, then he must enter novice 19t or intermediate stcok so that he can race at the same level.
