Last attempt to get R was a failure it seems due to the controller kept supplying amps to run the light so amps didn't drop as much then quickly had amps back to same with light off as on. More solar coming in than needed for batts.
Perhaps the early results were nearer the truth except for that inverter watts maintain thing.
My Absorption Voltage showed on the Tri as 14.4 at first then 14.5 the rest of the two hours, now dropped to Float. Lots of sun now so no problem with too late in the day, etc.
I suspect the temp comp is not zero at 25C but at some lower temp, because I have seen the 14.6 steady then drop to 13.8 but that would have been when cooler out.
Not long before dropping to Float, Tri was:
14.5v, 2.7a, -7.68AH
After dropping to Float:
13.7v, 1.7a, -6.91AH SG has risen a bit now 1.280-85
So it appears the batts are nearly full and the controller has it right. So my voltages vs SOCs were as seen, however that matches Salvo's graphs--not clear to me how that works.
Last laptop yank to complete the test is:
14.50, yank 14.70 then back down, so confirms yesterday's result at approx 0.2v spike when at Vabs set point.
Not sure what can be made of the day's other results, but it was painless to do! :)
