thats about it imho,

i also thought that you should always know your po2 when i first started diving rebreathers but it can be very misleading on scr where your fio2 is a much better indication of where your at and what the breather doing.
ccr you have to know your po2
scr for me beter to know your breathing what is comming out of your nitrox tank!
i did ring delta p about there scr mode on the vr3 as at the time it did'nt make much sense to any one but with a talk and a lot of thinking it all started to make sense!

So it is pO2 for CCR and FiO2 for SCR when trying to monitor you pO2 and also to work out you deco.
Knowing your expected FiO2 and your real FiO2 and MOD gives you safer diving because the planning will have been done with a pO2/FiO2 in mind.
