Usually each playback, but if it's a series from the same recorder
from the same time, and they sound the same running through I leave
it alone between actual tapes.

In case anyone has doubts about proper azimuth set to match the
original record gap, please see (and listen to the sample at):

How does this compensate for _record_ azimuth errors which is by far
the largest component of what we are correcting.
