OK the difference in your scenario is more or less 10 mins of deco. What I
would do is utilise my Standard Issue Mk1-A1 Brian and think about my deco
plan and the various scenarios that I had worked out before the dive.

Then, using the very same Mk1-A1 Brain, I would modify the deco schedule to
get out of the water a little sooner than if I had hugged the bottom at 180
for the whole dive. In this case most of the time is knocked off the O2 with
a minute here and there prior to that. This is not rocket science.

Why is this so hard? Does this really require a $1900 device strapped to
your wrist?
