Re: Standard Bailout Mixes

I am a new rebreather diver, with no He experience, so I have to stick to basic questions here. But it is obvious to me that bailout requirements are VERY different for O2/N2 OC, He/O2 OC, O2/N2 CC, and He/O2 CC divers. For any O2/N2 diver, why not just plan your max depth and choose the bailout's FO2 to give you 1.4 PO2 at that depth? But then for CC, some accidents are caused by over-exposure to O2, so would a lower PO2 make sense for CC divers?
If you take a MOD 2 CCR Trimix course you will learn that your diluent for bottom should have max pO2 of 1,0 so that you can lower pO2 by a diluent flush
