Many, many times I've read posts saying "I've heard that Cobra's are on the conservative side".
Well, it's easy to check, no?
I'm looking at my PADI RDP, and, for example, it says that the NDL time for a 90 ft. dive is 25 minutes.
Now, using my Cobra simulator (P0 Personal Setting), I draw a profile where I drop to 90 ft., and at around 21 minutes it shows my NDL time goes to 0. So that's conservative by 4 minutes compared to the tables.
If I do a similar profile using the Cobra's conservative Personal Setting of P2 (my normal setting), the NDL time drops to about 14 minutes. So that's 11 minutes conservative compared to the tables.
So it seems that, at least in this example, when using the Personal Setting of P2 it's "way conservative". Would you also call the 4 minute (P0) number "way conservative"?
