Sure according to bigger is better, but they won't actually accept that.
Alts are rated at maximum, real life is 50-70% output.

Because they don't make any bigger.

Not at all. Re-read what I said, and discuss one chemistry at a time.
Bulk means source is delivering maximum it can. With a weak source or high-CAR bank, that may be well below what the bank could accept.
Once setpoint V is reached (Absorption)
regulator holds to that as max V, and then eventually over time amps declines.
You can't generalize amp rates at SoC / time spent between the two stages, too many variables.
Measure and chart them for a given bank and charge source, sure.
