Daniel, What exactly is your plan? It could be that they are just planned differently. Are you planning to descend and then do 30 minutes on the bottom leaving the bottom at around 33-35mins runtime or were you planning of leaving the bottom on 30 minutes meaning that some (3-5 minutes) of that 30

It's not a comparison with Shearwater or your manual method but Baltic on the phone gives me 70% CNS and 104 OTU on a 74 minute runtime so very close to the Subsurface figures. iDeco Pro is giving me 64% and 84 OTUs on a 65 minute runtime (iDeco Pro i can't see the descent, it seems to start at 50m

CNS computing mistake

2023-03-07 Thread Daniel Miazek via subsurface
Hello Everyone. I think that there is a mistake in computing/calculating CNS. I've noticed this when I tried to plan a diving on 50 meters and 30minutes bottom time (including falling down), with 24litres air, 11litres nitrox 52%, and 6litres oxygen (nitrox 99%). I used Bulhmann algorithm wi
