Your points are well taken but my entry was an attempt
at pinning down *quantitative* differences between the
fit and the unfit diver in a simple but non-trivial model.
My suggestions were to scale the M values with the relative
mass distribution and scale certain compartment halftimes with
1/VO2 in a stock compartment model wo/ any additional
attention paid to any changes in any inherent/explicit
free gas phase modeling taking place in the model.


I cannot deduce if you think a gas-exhange model without
more attention paid to the free gas phase is just too far off
or you think the suggested scaling of the parameters are
wrong (the risk of bubbles forming due to supersaturation
in a tissue does not scale with the size of the tissue).


Yes, George, I know what you think.

John.
