"Hams are supposed to measure this? They can't even look up the rules properly."


I can certainly see where that measurement may not be all that 'exact', but it's certainly measurable by anyone with a half way decent receiver.  As for "can't even look up the rules properly", if you'd change that to "don't bother looking up the rules properly", I'd be willing to agree with you.  Sort of a difference there, wouldn't you say?


Signal bandwidths for particular modes is also fairly easy to find.  The way in which they are stated may have changed, but the 'widths' haven't.  Wouldn't figure I'd have missed something as significant as that, really don't think I did.  Or if they have changed, please show me/tell me where.  Can't find them in the current edition of Part 97?  Have you tried taking a step or two back from the current edition?  If it hasn't been specifically stated as changed, I have to think that thy haven't been.  That's how the rest of it works.
