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. My training on this was definitely in the camp of staying below 1.4 ATA always, and with GUE staying below 1.2 ATA during the working portion of dives.
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? Is using 1.4 ATA as a hard limit alarmist?
