On OC, I only checked a few times per dive as I was comfortable with my SAC rate and had a good handle on what my consumption would be.

Does the same thing happen once you get comfortable with CCR? Or do you not maintain your SAC rate due to the abundance of gas available to you? A related question to this, then, is -- does your metabolic rate of O2 consumption depend purely on a set rate based on your physiological demand for oxygen (at a given state of work), or does it fluctuate with the number of breaths you take. I would guess the faster you breath the more O2 gets absorbed by your lungs but would like to hear from those more experienced about this.

Thanks,
Paul
