In addition, lots of divers close their ADV at the bottom part of the dive.

In light of this discussion, should one be shutting their ADV off on bottom? Shouldn't one avoid doing so until the ascent phase begins?
Unsure about other units, but on the Meg a very simple/quick reflex completely flushes your loop in about 5 seconds (assuming your flowstop is already open).
