Fyi. I sketched out approximately that dive in the planner, 30min @ 70m 16/60, and there is no problem calculating the TTS on this i7-4600U @2.10Ghz. The calculation is instant and the TTS is at the "worst" point is about 226min. Maybe the planner is nicer to the TTS algorithm for some reason i can't figure out at the moment. Thats on OC btw, but you're dive is SCR? Maybe thats the culprit. //Anton -- Anton Lundin +46702-161604 _______________________________________________ subsurface mailing list subsurface@subsurface-divelog.org http://lists.subsurface-divelog.org/cgi-bin/mailman/listinfo/subsurface
