It was simply the shire number of references to part A, part B
then again A then C. Maybe the abstract letters don’t help. Could
you use more descriptive names every now and then?

<div class="">In the end, it’s not so complicated: The heat map
show how much gas is in the tissues compared to the ambient
pressure, all this as a function of time. Blue colors mean less
gas in the tissue and thus on-gasing, green to red mean excess
gas in the tissue to various degrees and thus off-gassing. Fast
to slow tissues from top to bottom. Lots of yellow and red mean
lots of seed for possible DCS. This is the general idea, the
more detailed version should be obvious from the figures (I
would hope). I would think being less explicit in the text would
help (because the reader needs to digest less information).</div>

The previous gas pressure graph was pretty precise and I could read
the exact compartment gas pressures from the graph and relate them
to the gradient factor (accepting there was no calibrated Y axis). I
prefer information that is as precise as possible, therefore this
preference. In contrast, for the heat map the colours are more
qualitative, but I still prefer as precise an interpretation of the
colours as possible. Therefore just a general notion of blue to red
is not sufficient. For instance, if I have a deco stage with orange
in it, I want to understand whether the inert gas pressures were
very close to the M-value or not. If the heat map cannot provide
that information, it would not serve any purpose for me. Therefore
my strong preference for a much more explicit interpretation of the
heat map. Because of this, it took me some time to get to terms with
the heat map. In addition, if I have never seen a heat map and I am
reading the user manual for the first time, I would like to have the
full explanation, not only a notional summary. The user manual is
most useful for divers using these facilities of Subsurface for the
first time. If I were that diver, I would have preferred the 'full
treatment'. <br>
I hope my approach appears sane.<br>
