Curious about this as I want to start using trimix. What is the minimum pp02 for a working dive that will keep you conscious?

I feel better after the dive if I keep my PPO2 bottom mix 1.2 max. That ANDI calls nitrox "safeair" is too funny. I know, lets add cyanide to whiskey and call it "safebooze".
