.. yeah, on the second dive we surface with a 79 min TTS value.

Which is interesting information, and I think it's ok to be slow for
the case where the diver may actually die.

So rather than say "screw it, don't bother calculating TTS past the
end of the dive", maybe we should just say "screw it, let's fix our
test dives to not be quite so deadly.."
