Battery Degradation of Florida 2015/SL after 23 months

Florida car here. I'm very surprised with how well the battery has faired so far. I plug in and set charge timer to be at 100% by 9am anytime I get home after driving it for the day. So far I've put 223 L2 charges on it over about 250 days (8 months or so)

According to CarFax our 2015-SL first arrived at dealer on 8/4/2014. It got transferred to another dealer AFTER 13 months on 9/8/2015. I bought it 11/4/2015. So when I bought it, it had already sat on a dealer lot for 15 months.

At the time I knew nothing about battery degradation. According to LeafSpy it had lost 5% capacity in the 15 months it sat on dealer lots. 10 days after purchase I bought LeafSpy and it reported
1QC
36 L1/L2s
AHr 58.58
SOH 94%
Hx 90.19%

Since then SOH had varied from a high of 95% to a low of 93% and back up to 95%.
Here are readings today. Odometer 4380.
1 QC
259 L1/L2s
AHr 59.16
SOH 95%
Hx 91.6%

BASED ON LEAFSPY READINGS IT'S PRETTY MUCH HELD STEADY IN MY 9 MONTHS OF OWNERSHIP.

That's encouraging, especially given the fact that it sat on a dealer lot (in the heat) at an unknown charge state for so long.
