1800 because my gas consumption rarely gets below 2000 even on long dives.I always have plenty of gas to spare for my buddies. AL 80 stage bottles I will breathe down to 1000 which saves back gas for emergencies
oh, another scenario, though it only happens once/year
Hydro/VIP time.... I'll keep my "reserve gas" in a bailout, and will run the main tanks down to 500psi, and just carry an AL80 for bailout. For something like this a nice big open cave is nice, JB etc, Orange Grove works as well because you can turn at a third then drop down to the deep cavern and burn the rest of the gas down there, but you run thirds on dive one, come out around half, then run in again to half of remaining plus 200, come out somewhere around 400-500psi or so. Keeps you from blowing off nitrox when they have to get broken down.
Certainly only something I do when it's time for the tanks to be broken down and it's easier to do in a cave than on a boat, and with a full AL80 I'm carrying right around the third I'd need if the 120's were full, and more than a third on any of the smaller tanks I use. Certainly the exception to the rule, but let the flaming begin.
What is this "psi" thing you talk of? Is it a bit like "vis"? We have neither of those here...
I wish we would switch over to bar.... I have a few bar spg's but don't use them because it confuses a lot of people during gas matching....
It depends on the type of dive. If solo I leave the cave with at least half of the gas I entered with, which means turning on thirds of my back gas carrying an equivalent third in a buddy bottle. With partner(s) I like to end up with 1/3 to 1/2 of what I started with. The tanks just get too light otherwise.

Is there a photo of your setup? Sidemount with Doubles seems like a ton of tanks. Or are you on a Rebreather with bailouts on your back? Inquiring minds want to know!

I'm pretty sure from his past posts on the subject he is scootering with backgas and one or two stages and only breathing the stage.
ahh yes... Russell uses the scooter.
