Amp Hours (Ah) is a measure of the energy returned to the pack during the charge, it is not the total of energy storage of the pack.

The number of Ah returned during a charge is entirely dependent on how much the pack was discharged.

The Remaining time and charge % are estimations that I'm pretty sure it uses the average of the past several charge cycles. That will or should get a little more accurate with more cycles on the pack and more data stored in the charger from each charge.
Personally I don't pay much attention to the time remaining since that always varies with how much the pack was discharged, and will almost always be different for each charge cycle.
