Scott, thanks for the chart! I dive warm weather/cold water, in other words central california, at least most of the time. For recreational diving I use a computer (the Vyper), and to be honest, the easiest way to solve this whole issue of gas uncertainty would be to adjust the CNS setting and the nitrox setting separately (one way is to just use 1.4 as absolute limit). That way one could err on the side of safety for both values. However, it would still be nice to have a very accurate measurement, just so that if/when the proverbial excrement hits the rotating blades device, one knows how to duck. All this discussion really comes about because the boat I usually dive on uses an analyzer that they calibrate to ambient air (1ATA). The reason is that they don't have a dedicated tank that is full of air. For some reason they don't seem to think this is a big deal. Maybe it's not. I just don't like "maybe's" in this sport.
