It did hold at 4, but something changed. An overnight FC loss test can rule out organics, and pinpoint the unit itself.
I'll perform an overnight FC loss test (with the SWG off) Thursday night (my night off). In the meantime, I increased the SWGs Cell Power Level to "3" per the Pool Pilot manual. That is max power and will ultimately shorten cell life, but running at 100% on Power Level "2" is doing the same damage.
We'll see. Thanks again to all of the TFP members who've helped me with this problem.
