@Capn Bloggs,
I agree that -3000 ft/min is a bit extreme. That was about an unpressurised airplane descent.
I was just responding to PH-Chucky's medical concerns : Even at -3000 ft/min there is no bowel implosion or lung crushing to be expected. The only issues I know of are with ears and sinuses.
IMHO, if the pressurisation system recovers about 1000 ft pressure differential at a rate of -1000 ft/min, the risk of ear pain is limited.
