the 8 hour period was just a guess on my part. i was simply looking at how long it took the pm to go into float, after doing its 15 minute (obligatory) boost, as per its programming. originally i started with 14.6 batt volts. the pm started at 43a and dropped to 33a in 15 minutes. (perhaps this means nothing?

Of course it means something. Tt means you were on the graph (see the one for the PM100 and mod-PM 100) where the mod PM 100 was at 14.6 and 43a. That is where you were in SOC on your four batt bank (same as mine more or less)
the battery bank would only accept 43 at 14.6---that tells you what SOC you were at. then in 15 min it went down the curve to 33a and then crashed to 13.6v and now it would only do that amps and taper from there.
------------------
and that's one thing i hope to find out by starting at a much lower SOC.) so i figured, the 75a pm might take 2 - 3 hours to boost.
------------------
You already know how long it will take to go from 50-78% SOC. That is 28% of 430AH = 120AH. At 75 amps constant, that will take 1.6 hours.
----------------
then i guessed the peak would take 4 - 5 hours to do its thing in abs. and, i would need time along the way to take readings. so i figured about 8 hours total with a 14.6v / 75a boost, and a 14.6/8?v / 40a (then tapering) abs charge. i guess time will tell. (no pun intended)
