To those physiology gurus out there,

I have been pondering this question for a while now.  Please consider this
scenario:

You're on a deep dive in cold water.  You're wearing your drysuit with
normal drysuit underwear.  When you have incurred a significant
decompression obligation, you accidently rip your suit on a jagged piece
of metal, and it floods.  You immediately abort the dive, but still must
do your decompression.  On the deco line you start to become very cold,
and due to the cold, your off-gassing efficiency is significantly reduced.

Now the question.  How can you tell the point at which off-gassing
efficiency on the deco line falls below the off-gassing efficiency
that would exist if you were in the dry, warm cabin on the boat breathing
100% O2?  Can you tell?  Is there a mathematical temperature model
that would tie into whatever deco algorithm you're using that you
could use to determine this (or the optimal deco profile under
your circumstances)?  I suppose that this is a highly individualistic
thing, but perhaps generalizations could be made?
