L2 Charge taper between 90 and 100%?

Does anyone know how long it takes takes to charge between 90 and 100% when using 32-40 Amp L2 charging?

When I've charged from 90 to 100% in the morning before leaving on a trip it usually takes about 1 hr 15 minutes. If the last 1 or 2% hasn't finished by then I don't wait for it.

Here is a graph of my M3 RWD taking it from 90 to 100 using my Wall Connector which has a 60 amp breaker and supports 48a of charging.

Note that once you hit the taper point it does not matter if your charger is 32a or 48a. If the car only wants 30a for the battery at that moment it is only going to draw 30a. So you could improve on the charge time just a bit for the first part of the charge, but once you are into the taper it makes no difference.
