I will spout out what should be important here to us closed circuit divers: the VCO2 column which indicates the volume of CO2 produced in liters per minute.
For most of the VCO2 columns in these exercises, Rob's CO2 production does exceed 1.6L/min. But of course, the stuff that they make Rob do are significantly above the typical physiological exertions rates encountered by an average diver on an average dive. Rob, too bad there is no heart rate column, or did I not know which one that was?
A little thread hijack here...
How is this: want to increase your scrubber duration up to an additional 30%? Easy. Go on a low carb diet before diving. I am not sure if I would need to worry about that with my large scrubber, but I would think that others with smaller scrubbers might find that useful.
Metabolism of protein produces 15 percent less CO2 than carbohydrates do, and fat produces about 30% less CO2 per liter of oxygen consumed.
Reference 1. Reference 2.
In the second reference, it indicates that the metabolism of alcohol produces even
less CO2 than fat. As far as scrubber time, then, a good pre-dive meal would be steak cooked in butter and a sour cream omelette chased with a nice cold glass of vodka.
