ditzpro, I had a Signature Model S P85 that went from 265 miles at 100% to 220 at 100% after 3 years with maybe 24,000 miles on it. I was charging in that 60 to 80% range and not driving very far between charges. I was very concerned. Hearing that balancing occurs at levels above 93%, I started charging to 95% regularly, never leaving it at 95% for long, but gradually over the course of a couple of months of consistently charging to 95% and driving almost immediately, that 100% went back up to 250 miles. Not saying it will work for you, but you might try it.
