Discrepancy between my computers during the dive

Oxygen Toxicity

Oxygen toxicity happens with partial pressures overwhelm the body. Severe cases of oxygen toxicity could cause cell damage or other symptoms.

You can find all kinds of opinions on how long it takes to "reset the O2 clock" and how fast pulmonary O2 danger passes and whether or not the buildup affects CNS toxicity as well as what are safe levels of O2 partial pressure.

Thanks, the DAN article does not mention the NOAA exposure table or the half life of O2 elimination vs. cliff vesting after a 24 hour period.

Shearwater and the CNS Oxygen Clock

The question of what CNS oxygen exposure is safe can spark heated debate among technical divers. This reflects the seriousness of CNS oxygen toxicity when diving. This article sidesteps that debate, and focuses solely on how Shearwater dive computers calculate the CNS value.

That's what I said. There are lots of ways of looking at it. Nobody knows what is correct.
