Mr. Hanssing, these are all very fair points, but all points covered in Mod 1 - at least in principle. The devil seems to be in the execution. In the oxygen consumption poll on
http://www.rebreatherworld.com/gener...er-minute.html
plenty of trained ranks appear to be running consumption rates of 2 litres/ min, while some claim to be below 1. I would be willing to bet that they are all aware of the points you make and attempt to implement them. What do people who use less than 1 litre think they do differently?
The poll you reference, concerns actual usage and not metabolic rate. But assuming metabolic rates are more or less in the same range [0.75-1.1 l/min] for average divers, then the rest is down to how much gas you let bubble away OC.

I've found about 2 litres per minute based on 50m dives for around 70 minutes. This includes flushes, is my bailout O2 reg working tests and the like.
So methods for reducing this amount, includes the topic I mentioned before, and keeping OC/loop flushes to a safe minimum. The longer dives you perform the less waste pr. dive-minute, and therefor you get a better O2-rate.... But that does not give you any ideas for your type of dive-profiles, which we can assume are fixed.
So to lower you wasted gas, follow you MOD1-training, get perfect at these skills. Especially during ascent.
To lower metabolic rate - go to sleep/into trance/hit your Zen/loose your muscles
