Someday I am going to have to try the 4 hour run time without stirring, the PPM and particle size must be BIG :-). I'm guessing here as I can't measure either :(. > I think the uneven wear started due to my contaminating the one > electrode more than the other by touching it more with my bare fingers > before immersing it into the unit in the DW.

I think this is possible, but I'd be willing to bet it is something we all do (manually adjust the electrodes). I know I do it. I haven't run as much CS as you have and my electrodes were not measured comprehensively to start with, but, in theory, they were 0.040 (18 ga) to start with and I am now measuring variances of from 0.030 to 0.40 with most readings around 0.036 - 0.038. I would think that the 4 hour run times would have more to do with it as a guess. The one thing I have noticed since going to the two 14 gauge electrodes that makes no sense to me is that my electrodes are two distinctly different colors - one is dark grey and the other is a noticibly lighter grey after not being wiped off after the last batch and sitting for a few days. Last time I looked at them it appeared that one was the dark grey and the other a medium tan (within a day or maybe two of the last batch). I am switching on a 50% duty cycle so it would seem to me that they should be indentical. Incidentally, both electrodes were cut from the same piece of .999 silver wire.
