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.
