In that vein
Back in the deep stop days I was gas diving with a group who had total control over the boat and we usualy ran 3 hours sometimes 4 so 45mins at 70m was a typical dive profile for me. I tended to run what ever profile ended up with a 3 hour run time.
Since switching to fewer and now no deep stops my diving has changed considerably due to the max two hour restriction imposed on most boats thease days
Also theres not so many easy access deep dives, I don't have any great need to go deep all the time and bang for buck shallower is better on a 2 hour max runtime. So the shift in my diveing has gone from 60-80m mainly to 40-60m mainly and fewer of them
So by the time I got to 80/80GF I was firmly in the latter camp.
Would I run 80/80 on a 100m dive?
Probably not. but I'd be more inclined to run 70/70 rather than 50/80
Profile wise. 1.3 set point 20m END max and last 20mins of any profile on pure 02 CCR and stay on o2 to surface / ladder and for 5mins after sitting down on the boat (longer if getting on the boat was a struggle)
