I'm not trying to start a fight or call anyone stupid. I'm just trying to point out that inexperience will make it harder to even know what lesson to draw from something that went wrong, or how to fix the problems with running races for beginners. My point was just to emphasize even more strongly how dysfunctional it is to just throw the n00bs into the deep end and let them sink or swim. But I also think that Cat 5 is part of a good solution to training new racers, and that mixing it with Cat 4 from time to time doesn't render it useless.
