^^ I have to agree with you on this one, a supercharger is just as adjustable as a turbo, if not more (a turbo can only spin as fast as the exhaust going through it)
And for the comment about turbo's not limited to engine speed:
Are you saying that turbos are putting out the maximum boost that a particular system needs at idle? And that everything else (any increase in boost pressure) after the exhaust volume/speed increases (usually happens with an increase in rpm, aka engine speed) is just sent out the waste-gate,
in theory: at idle you are making 10psi, which is all you want, and when you are accelerating and the engine is at 3k rpm you've got 20psi, but half of that is getting sent out the waste-gate?
and for the altitude part: yes they might be effected differently, but as stated, both are adjustable
