AGM vs Flooded Bulk Times
PT keeps asking whether AGMs will spend more time in Bulk at the same charging rate. I found a good example where that can be measured, using ah64id's test with his PD4655 on his pair of Lifeline...

But for the first while, they should both be accepting 20a, gaining AH at the same rate, like your idea earlier of two different cars both at the same speed.
Won't one be accepting more of the 20A than the other? say 19A compared to 17 for ~1.5 hr? The AGM continuing to get 19A for a while longer?
I didn't allow for any heat loss difference between the two types of battery. The Trimetric manual says they tested some Wets in the mid-SOC range and they had hardly any heat loss. That changed big time when above 80% SOC.
So it might be that heat loss would not be a factor for the shorter time (I assume) the Wet stays in bulk from 50% to X %.
