Argh! Tough task :)

I saw Willem warned about user manual being complete...

If Dirk push this patch I think we should have some explanation of how
TTS is calculated. 4.4.2 user manual says:

Clicking this button causes the Information Box to display the No-deco
Limit (NDL) or the Total Time to Surface (TTS). NDL is the time
duration that a diver can continue with a dive, given the present
depth, that does not require decompression (that is, before an ascent
ceiling appears). Once one has exceeded the NDL and decompression is
required (that is, there is an ascent ceiling above the diver, then
TTS gives the number of minutes required before the diver can surface.
TTS includes ascent time as well as decompression time.


I would mention that TTS is calculated assuming an ascent breathing
the gas currently used. . Even if the profile contains several gas
switches, TTS at a certain point is calculated with the current gas.
TTS calculation is a very cpu intensive task hence Subsurface will
calculated it only if it is less than 120 minutes. For TTS longer than
that Subsurface will indicate TTS > 2h



PS #1

Figure A and B mentioned in the user manual on my pc are nearly
unreadable. BTW figure B does not display TTS

PS #2

Searching for TTS in the user manual I remembered this old Windows nuance:

http://trac.subsurface-divelog.org/ticket/797

I do not know if somethign has changed on Win 10 or even Win 8. I'm on
Windows 7.
