Amps jumping around on AGM finishing charge
At a battery temp of 81 degrees and a float charge of 13.33v, the charge was settling in toward .1 A when it started jumping around more and more. Still settling, but jumping from .02a to .15a. The ...

I am about 70 percent sure this correctly indicates recombining of hydrogen and oxygen internally in the catalyst at an accelerated rate, before release of gas by the valve. I just reproduced it.
Temp works to control outgassimg but is the crudest indicator and generates many bubbles after removing power. Water over valves - fewer bubbles but still more than I want. Multidigit jump in hundredths of amps up and down, no bubbles but same situations that generate bubbles, such as running voltage up to charging voltage on nearly full battery.
I am happy. It was a good day for useable experimental results.
