"If they were more discharged at the start of the charge cycle, they will need to spend more time in Absorb."
In that case, they would need to spend more time in bulk/cc... Abs/cv would not differ. Charge Rate and Vabs setpoint decide how long Abs will take, not dod beyond the transition from bulk to Abs.
Real World vs. Marketing
Like I've said, a 50-100% charge at a 10.5% C-rate will cause amps to taper (i.e; go into abs) at 89.5% soc, and a 70-100% charge will likewise cause amps to taper (i.e; go into abs) at 89.5% soc. The numbers don't lie. The depth of discharge beyond the point of tapering is irrelevant, regardless of what any marketing strategy would suggest.
