UTTER and complete rubbish. If you're referring to the difference between an rms
and peak voltage or power, that's already taken into account in the speaker's
rating. Yes, you can get a bit more out of an amp on toneburst but rarely much
over 1-2dB at the very most. Certainly not for long enough to do any damage.

You're straying into tech territory here George that you don't understand. Stick
to rigging and mixing.
