6.6 kW EVSE ?

32 amp EVSE - so limited to the cars 6kW OBC. As the battery health deteriorates, the formula gives more % charge, but it is close enough.

Once again our stats have crept back up after just a few long driving days and repeated re-charging. The last time I did this check we looked close to dropping our first bar - now I am not so sure...

We don't have a quick charge port, so all charging is L2.

Todays numbers:
AHr=56.41
SOH=90.17%
Hx=83.87%
SOC=97%
odo=8850 miles

My numbers are very similar to yours for a car with about same use.

Me too I have noticed that numbers go up when i drive more. I don't see any significative degradation of my 2015 pack since June 30, 2017. My numbers were going up during the summer after some trips needing to recharge.

AHr=56.15
SOH=90.42
Hx=83.36
Soc=97%
odo=16064 km

I generally charge on L1, sometimes on L2 or L3. 18 Qc, 615 L2.
