There is no wriggle room.  So long as you accept a modern definition
of PEP, it's clear that max, average, RMS and PEP are identical for
all practical purposes.  

The definition for PEP over here is "the average power during one
radio frequency cycle at the crest of the modulation envelope taken
under normal operating conditions".

You'll see there is no mention of mode in this definition - there
doesn't need to be.
