Hi Robert,

I really like your effort, and  the realization that there is room for a 
million improvements :-)

As Davide already mentioned, 26 minutes is way too long, unless is it 
very structured, divided in chapters, etc. A "total planner course" 
could easily be this total length and even longer, covering more 
advanced type of diving.

What I would like is a different point of view. Define a "problem" 
first. Such as: we like to plan a recreational dive, we like to look at 
differences in VPM-B and Buhlmann, we like to plan a dive to 80m with 
20min bottom time, and like to compare different bailout scenario's for 
that. And with that problem defined, show how it can be planned using 
the planner. So a little opposite as the style it is now. Now, it 
explains more or less way the program works, and not from a diving 
problem to start with. Obviously, we should not try to make "an online 
dive course", but I would like a "dive planning problem" to be central.

What I do not like  (and some parts of the user manual have the same 
"issue"), is that examples are given that are not considered save diving 
practice (any more). Such as deep air, not respecting MOD of gasses when 
pointing and clicking trough a dive profile. And the striking example 
from the user manual (ok I get side tracked :-) is a PSCR dive with the 
last 20 minutes of the profile in the hypoxic zone of the selected gas. 
Like I said on github: do not try this at home.
