The 98% reading on a "full" charge is normal and means pack was under the impression that more balancing was coming. I saw the same on my car and guess what? The move from 98% to 100% REDUCED my GOM by one mile.
Either way, its a waste of time to wait on 100%. I only did it because I didn't set a timer and had no appt so I pushed the issue.
I still am curious what the Leafspy reading is for a true empty pack. 0%? 5%? what is the lowest anyone here has ever gotten down to?
tl;dr
0% remaining per LeafSpy is when a cell hits the anti-bricking voltage.
The thing to keep in mind here is that capacity** is defined as the AUC (area under the curve) from a maximum allowable cell voltage down to a minimum allowable cell voltage where the car shuts down. Your question then can be phrased as "is the shutdown cell voltage the same as the dead_and_killed cell voltage, and second, which low cell voltage does LeafSpy use ?
So far as I know (@GerryAz ?), the reserve to prevent bricking is a voltage allowance that is not reported by the Canbus (and therefore not by LeafSpy.)
It isn't hard to figure out, by the way. Check the cell voltage histogram at a SoC below 5% and compare the low cell voltage to the industry standard capacity test parameters.

At a defined C rate, but skip that detail for now
