I'm sorry but you're wrong. In davehicks post he claimed:
a calibration in response to a wet cell or faulty connector will mask the problem, NOT fix it. This is a common misconception but one that needs to be corrected because it is dangerous!
If you record the millivolts in O2 at the beginning of the dive and they are different at the end of the dive you have a cell problem not a calibration problem. Cell failure seldom shows up during calibration because current limiting commonly occurs above 1ATA.
I didn't take it to mean surface, calibrate, and descend. I took it as end the dive. The recalibration would be at a later time, say, the next time you build the unit. Recalibrating with a wet cell will even further exacerbate non-linearity. Most likely meaning you'd never get a viable reading in air anyway. I'm not sure how it would mask anything since you're literally throwing every other reading out of whack at the same time since you're not doing a 2-point calibration.
Guess it depends on what he means. I assumed what I did because no one in their right mind would re-dive a unit with obvious cell problems. Maybe I assume too much. Then again I'm not the kind of guy that throws his unit in the back of a truck, throws it in the corner of a garage, and picks it up in a week to go dive it without doing anything else to the unit.....
