My LeafSpy data are now 55.16 AHr, 84% SOH and 69.27% Hx. I don't know if all of the "exercise" increased the battery capacity, but I cooked it pretty good on the first day of the trip from Kennewick to Astoria.
Now our numbers are even closer. Mileage, capacity, everything. I'm at 21,900 miles and 55.22Ah. I still have all 12 capacity bars, but I don't think I'll keep the top one much longer.
FWIW,
some of the MY2013 owners are reporting their capacity goes up after QCs:

then next week comes. have 3 days of 90+ mile commutes. see small increase in ahr every day with big jump (1.81 ahr) happening on warmest day which also was day after longest commute (96 miles) Shortest commute for the week was 74 miles. I end up at 66.81 ahr from 63.73 ahr.
then comes 3 day weekend. back to driving 25- 40 miles a day and today my ahr is... hold on
is 64.24 ahr. now am i worried at the seemingly 4.6% loss of capacity? or actually not sure how we would measure this because one method would be ahr from 67.36 for new to 64.24 or we could use a much nicer option of 3.1 % loss due to having only 22 kwh instead of the new 22.7 kwh?
now, I present this as information and contend nothing simply because I really don't know what all this means

I started out with AHr=62.13, SOH=95%, Hx=95.69%.
After two days with 4 or 5 short quick charges each, and about 400 miles of driving, I was at AHr=65.54, SOH=100%, Hx=100.26%.
Then I drove one or two quick charges per day for several days, and noticed the numbers going back down a bit.
Finally, a couple days ago I performed 7 quick charge sessions in less than 12 hours (and drove 275 miles in between). Then the next morning I did another 100 miles or so with 2 short quick charges. I ended up with AHr=64.93, SOH=99%, Hx=100.25%
Now that we're back home, I'm going to be driving my normal 25-30 miles per day and expect to see it fall quickly back to the 92-95% ranges.

However, multiple QCs on other occasions have not resulted in any bump in AHr capacity. I don't have QC in my 2013 S, so don't have post QC data for that car, however, in May this year, my S did have an unexpected jump in AHr capacity, also from 60.87 to 64.33. Completely unexpected and capacity also dropped to the usual 60.5-62 range afterwards. Maybe some freak bug in a version of LeafSpy, since the bumps were about 1 month apart?
