Not sure what "open glottis" is but will google it. But it sounds like you are saying to hold your breath slightly, which I thought was a huge no-no.
Just breathe.

Many variables to air consumption.
Body mass
Relaxation level
Temperature
Depth
Trim
Exertion level
Fitness level
Breathing efficiency.
My best ever consumption was 0.36 cuft/min warm water zero exertion, worst was 0.95 cuft/min cold water, shivering, turned out i had a 101 fever when I got home.
I usually run 0.5-0.6 warm and 0.6-0.7 cold.
6 ft and 185 lbs
My girlfriend consistently has much lower gas consumption than me.
I have started just opting for a larger tank when I can which keeps us closer to even.
I dive a 100, she dives an 80
Most of my dives are in pretty warm water with a few colder dives in California, Galapagos, etc. My average RMV for my last 1400+ dives is O.36 +/- 0.04 cu ft/min (mean +/- std dev). I have just under1900 dives, my RMV has improved only a little in the last 9-10 years.
5'10" 185 lbs. My best is 0.27 cu ft/min on a couple of divesDamn!
5" 6' 135lbs?
;-D

Yeah. I don't think my consumption rate has changed much, if at all, since my first dives. I don't think I was doing a lot of unnecessary movements, etc. and wasn't overweighted. Maybe all that snorkeling for decades before helped. I just don't think about breathing, but am well aware of how quickly a tank empties if you are swimming fast to cover a lot of ground (which I rarely do).Just breathe.
Or using nitrox?Yeah. I don't think my consumption rate has changed much, if at all, since my first dives. I don't think I was doing a lot of unnecessary movements, etc. and wasn't overweighted.

Oh, maybe I missed something-- according to the old tables, the Air limit at 60' is 55 minutes, so I hope you hour guys are doing deco stops. It's probably not a good idea to push it to like, 54 minutes either.
Well yeah, but they're all talking air.Or using nitrox?
