See the attachment. > Yea, the thing is that the TTS calculations doesn't do gas switches, and thats pretty much by design. IE during your 80m phase, you have a TTS which is enormous, because it calculates how long it would take you to reach the surface on the gas your currently on. My suggestion here is that we cap the TTS at something like 120 min, and abort the calculations if its longer than that, to limit the amount of calculations needed to be done during that phase. Yea, someone might be interested in knowing that their TTS is 1200 min or so, but its not that useful. Its just a waste of cpu. //Anton -- Anton Lundin +46702-161604 _______________________________________________ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
