No disrespect meant to yourself @rjack321, but I am simply stunned that folks would think (or now think / are taught) that 1.35 is a 'relatively high' po2, CCR or otherwise, unless one was doing very extensive long duration dives.It was explicitly part of my crossover in May 2018, including adding the shutoff to the stock MAV and "breathing down" a higher ppO2 (e.g like 1.35 down to 1.2).
