I have a hypothetical question...

If only 1% of the CCR dives resulted in requiring OC-bail-out from the bottom to surface, how many people would be willing to accept this risk for the sake of diving uncumbered without stages knowing that if they have a loop flood, they will die ?

That means 1 in 100 dives, so could be a high percentage. So let's reduce to 0.5%, that means 1 complete loop flood in 200 dives.

Or let's say 1 in 500 dives ? Remember it could happen anytime between dive 1 and 500..

Who would take this risk ?

I know a few alpinist divers. Some are just lazy and complacent, but some are fully aware of the risk but willing to accept the percentage.

I know you didn't ask about alpinist, but IMHO, there is no such thing as semi-alpinist (i.e. like semi pregnant) so either you have adequate OC bail-out or you don't. So having a small amount of off-board gas just to take "sanity breaths" is alpinist in my book.

What would someone do when after taking a few sanity breaths, they realize that they can't get back on the loop and not having adequate OC-bail-out ?

Back to the old chestnut of 'do you include inboard' in your bail plans or not?
Personally, I conside OC bail to be 'last line of defence' so assume complete and catastrophic failure. If the inboard is in tact then its a bonus in the fact that I have some 100% for the 6m stop. The rest of the inboard is just sanity breath to the BOV.
I tend to keep the He content of the primary bail the same as the Dil. How much bail is a matter of new debate for me. When my mate John had a Co2 hit, his RMV hit 90. I have to conclude that planning bail on normal to slightly elevated RMV is not the best idea.
