I want to derail your conversation by going on topic again.
Recap:
0-50 meters is Nitrox
70-120 meters is Trimix on OC or CCR
CCR makes sense if you dive alot.
120 and beyond is CCR
50-70 meters is the weird range for OC because of the cost of Helium. If Helium was cheap and easily available, this depth would be Trimix. Since Helium is not cheap or easy to get, some OC divers go for it with Air and accept the added risks. Others, find this risk unacceptable and choose not to dive recreationaly without Helium beyond 50 meters.
Is this a correct summary of the argument?

for yes and
for no
