What O2 partial pressure do you use for Nitrox Calculations

The Cobra and other Suunto computers will let you violate the NOAA 24hour CNS limits and still show you as being well into the green zone of the CNS bargraph.

If you were showing 3/4 of max on a Suunto,then you probably had exceeded NOAA limits.

Which is it?

Sorry about not being clear.

My point was that dive computers are much more liberal than NOAA 24 hour limits, and that your dive computer may show you with relatively little loading while in fact you have exceeded the 24 hour NOAA limit.

Suunto's use a 75 minute halftime decay to clear the CNS clock. Oceanic/Pelagic uses a more conservative 90 minute halftime. NOAA table just sums all of the CNS loading over the past 24 hours.

Whether Suunto, Oceanic, or NOAA or WKPP is correct is a different discussion.

Does anybody know what GUE currently recommends?
