Battle Born Charging
This might answer some recent questions. The table is not accurate wrt to the BB comments--don't go by it by the table itself. Wade through the questions and answers to get the true picture. Tak...

Tommorow I'll probably drain my battery down all of the way and then charge back up from there documenting all info.
That's with the inverter generator and trying out the second charger too I hope. You did get about 68AH doing your "30-70" though, so that came out right. Yes, you should get faster time doing a 30-70 with the amps not tapering from the start.
We do 50-80s with generator charging with lead- acid batts to keep gen time reasonable for the AH you get. The Li advice was to do 30-80s taking advantage of being able to draw them down lower while they still keep up a good voltage. 80 limit there was to not stress the Li, not because of generator waste of gas.
EDIT--thanks for the additional graphs and data Itinerant1. More grist for the mill! Note that the spike in voltage at the higher SOC zone on the curves is similar to what happens with lead-acid batts, except with a higher SOC zone with Li looks like.
"Gassing voltage" with L-A. No gassing no bubbles, no mixing. AGMs need some 14+ to fill the glass mats. BBs need 14+ to get their BMS to balance. Different reasons to do the same thing.
