Narrative:
Participant in airshow with aerobatic aircraft. Climbed to 5000 ft AGL to start air show. Waivered airspace in effect at XX00 local. Altimeter has to be set on AGL to do aerobatics for safety. No time if set on MSL to do calculations about how high above ground when nose pointed straight at ground! Checking later realized waiver was to 5000 ft MSL, oops! Sorry I'm professionally human! Ps: reason start so high -- stopped the propeller to do aerobatics at deadstick landing.
