CNS can be higher than 255%

2017-11-09T13:43:57Z

I'm sure this bug has heen here forever, but the CNS clock is not very relevant for most divers, and even some technical divers do not care about this value. However, doing long decompression dives, the value can easily grow over 100%, and a lot further. For example, the OSTC computers use 2 bytes to store the CNS value in the profile data, and I have multiple dives in my logbook going way over 255%. This all said. Just store the CNS value in an unsigned 16 bit. Signed-off-by: Jan Mulder

Planner don't add minimum gas switch time more than once

2017-11-09T09:43:03Z

Avoid adding the minimum gas switch time more than once even if we skip some available deco gas. Signed-off-by: Stefan Fuchs

VPMB: calculate time of final ascent properly

2017-11-08T14:22:32Z

Commit d15779a calculates final stop based on stoplevels[2], but if final stop is 6m/20ft, we should use stoplevels[3]. This fixes it. Signed-off-by: Rick Walsh

VPMB: time_clear_ceiling is only valid after time_deep_ceiling

2017-11-08T14:22:32Z

Some messed up logic was producing negative deco_time values for some no-deco dives. The CVA wouldn't converge and unrealistic VPMB ceilings were displayed in the profile. This fixes it. See #762 Signed-off-by: Rick Walsh

VPMB profile: remember deco_time when restoring deco_state

2017-11-08T14:22:32Z

Otherwise the CVA won't iterate properly. Signed-off-by: Rick Walsh

VPMB: final_tts may be calculated before final sample

2017-11-08T14:22:32Z

We calculate tts every 30s, not every sample. Consider that when determining the time that the ceiling would have cleared if it's after the surfacing time. Signed-off-by: Rick Walsh

VPMB profile: use deco_time rather bottom_time from planner

2017-11-08T14:22:32Z

This makes the calculations in profile.c a little simpler, especially now we adopt consistent final ascent rate to determine deco_time since d15779a27 Signed-off-by: Rick Walsh
