Hi @wnissenApparently, I have both above and below average consumption. At the end of a week in Cozumel this summer, with no wet suit, I was down to around 10 L/min. This weekend in Catalina, 8/7mm suit, hood, 3mm gloves, surge, current, etc., I was a bit over 20 L/min. In customary units, .35 to .75 ft.^3/min. So I encourage everyone to take the data here with a huge grain of salt.
Or, your average gas consumption balances out the different environments you dive in and the different equipment you use. You use the average to predict about what your gas consumption will be.
If you know you are diving in Cozumel, plan accordingly knowing your previous performance. If you will be in Catalina, do the same thing.
I have my RMV for almost all my dives since 2010, 1792 dives. The avg is 0.36 cu ft/min with a std dev of 0.04 cu ft/min. If I'm diving with my wife in Bonaire, I know my RMV will mostly be around 0.3 cu ft/min. If I'm doing one of my solo drift dives in SE FL with brisk current, cold water, poor vis and am carrying my flag and camera, I know my RMV will be in the low 0.4s cu ft/min. Plan accordingly.
So, for your two trips, your average RMV is right about avg, around 0.55 cu ft/min. You go back to Cozumel it will be on the lower end, back to Catalina, closer to the high end. You appear to have a lot more variation than I do, but you also appear to have less dives. It might also be helpful to keep track of range so that you know the extremes, My range is from 0.24-0.63 cu ft/min. The lowest was mostly kneeling or standing in the sand watching Great Hammerheads in Bimini. The highest was the opposite, a cold, dark, high current dive on the stern section of the Chester Poling in a wetsuit in Cape Ann, MA.
I did not start recording my RMV until I had about 450 dives, my RMV was already pretty well set where it is today, just a little lower with less variation. I would imagine another experienced dive, like @tursiops, has results that look somewhat like mine, and are used similarly.
Best of luck with your future diving.
