PD4655 Charging Graph
I have been reading quite a bit about different converters and charge rates, specifically some claims that PD's seem to drop off earlier than other brands. That is not what I have noticed on my setup,...

It doesn't match my mfgr data, I think I'll stick to what the manufacturer put out.
The manufacturer is Concorde. Lifeline points this out here. And Concorde has a different figure for their batteries that also match everything else I've read on AGM SOC voltage figures. So I was simply applying the preponderance-of-evidence rule on this one here.
You may be right, though. Not worth arguing over for me. Your batteries, your experiment.
Nope, not sure why that's important thou?? I was still pushing 4A when I went to bed that night, Lifeline says I need to be below 1.5A to be at 100% and that takes several hours more. It takes about 12-15 hours to get the ammeter to read ± 0.0. The test was not a time to 100%, rather showing that my PD4655 will push 55A until the voltage on the circuit board hits the set point of 14.47. It does, and that took ~90 minutes.
Most battery charging while boondocking is not to 100%, it just takes too long for everyday use.
Absolutely.
And it may be possible to eventually get to 100% at voltages below 15. Some folks say no. I tend to think yes... maybe... but I like to get them into the 15s before I put 'em to bed. However, this requires disconnection from the coach.
