Here is a rearrangement of your diagram that is possibly more logical if
one starts the explanation of the heat map by refering to the gas
pressure graph. A few points:<br>
<br>
1) The ranges for offgassing and ongassing on the righthand side need to
be demarcated at the light green zone (0% of M-value). If the
demarcation corresponds to the black zone (100% inert gas equil
pressure) then there needs to be an explanation of for the colours
between black (100% inert gas equil pressure) and light green (ambient
pressure).<br>
<br>
2) I omitted the word Bühlmann from the lable "M-value" because this
ties the diagram very solidly to the Bühlmann algorithm and not to the
VPM-B model.<br>
<br>
3) I added % symbols to the scale values on the right of my version of
the diagram in order to make the captions e.g '% of inert gas
equilibrium pressure" more immediately understandable.<br>
<br>
A question from a naïve diver who knows nothing about the VPM-B
calculations. In which way is the M-value part of the VPM-B algorithm?
In other words, does it depart from a Bühlmann point of view?<br>
<br>
Any comments, please?<br>
Kind regards,<br>
