On a recent live aboard to the Cocos I found that everyone excepting myself was using a ppO2 of 1.6 ATA as a hard limit. Most of the divers onboard were from Europe or the Near East. In practice there was little prolonged diving below a ppO2 of 1.4 ATA.
What do you use as your limit? Does it make a difference to you if your peak ppO2 is significantly above your average. Do you treat ppO2 as a hard limit, or as a dose limit where both pressure and time come into play? If you are using something less than the NOAA limits what is your rational?
