Originally I thought that a reverse profile referred to a dive
during which the deepest part is reached late during the dive
(for example 20 minutes at 10m then go down for 5 minutes at 30m
before ascent). From the usage I see here and there, this does
not seem the case. So how would you call such a dive profile.
Inverted profile?
