Hmm. We try to remove time at the surface in the middle of the dive
from the SAC rate calculations, but we do that by just modifying the
dive time.

Which is makes some sense, but at the same time the average depth of
the dive has been calculated without that dive time modification.

So for dives with extended time at the surface (happens if you dive
down a bit for a buoyancy check and come back up to wait for your
buddy, for example), our SAC-rate calculations are slightly off.

I'll look at that, just in case.

At the same time, I wouldn't be surprised if Suunto DM just had a bug too.
