OK, except for two trips to the Outer Banks 400 miles each, the run up to Toronto and the drive to Charolette NC the only other 200 mile plus drive was our weekly trip to Baltimore and that when on from September of 2015 to February of 2016. I also did the Reach The Beach Rally last year, that amounted to 300 miles for the week-end give or take a little.
My normal drive day: 3 mile round trip to the train, may be a trip to the super market and on the week end a ten mile trip for shopping or dinner. And, yes, there are days when I put on a couple hundred mile in a day. However,I can count on one hand the number of time I did a 100% charge, and yes I jump on a supercharger once or twice a month. We did put on a ton of miles between September 2015 and February 2016. I don't think that should affect battery degradation.
I keep hearing that the rate if decline will slow down, but I have not sen it.
