I agree, and I think that this is the point I was making in a roundabout way, but the hand up supplements the whistle in case of excessive noise. This is the theory, is it not?
If so, what has changed to make that theory less applicable now and why do some say that this signal could/will be dropped? I understand about PT, (sorta) but we won't see that at high schools around here in my lifetime.
