Yes, see the attached chart which shows an acceleration the last couple years - I attribute the acceleration to an increase in commute miles and increase in charging to 100% instead of 80% in addition to deeper discharges.
2011-2013 my commute was shorter - about 22 miles. You can see the blip in 2013 caused by the P3227 update. In 2014 I worked from until the fall and then commute increased to 30 miles. Started off 2015 charging 80% most of the time, that gradually increased to now where I only charge to 80% one day a week when I know I don't need the range, primarily just to get the GID number. It appears that either rate of capacity loss is increasing, or a combination of that and more time at 100% SOC is causing the rate of capacity loss. With the battery in it's current state, the lack of regen combined with tires that don't appear to be all that good in the rolling resistance department, charging to 80% gets me around 26 miles to LBW.

I did that Monday. They say that it's a one-time process and they don't ever re-open the discussion for re-analysis. Once you open a case for a particular problem and your request for assistance is denied, they will never reconsider. There is no way to escalate it through the EV-hotline. The dealer tells me a similar story - there's nothing they can do to help - my only option for out-of-warranty assistance is to go to Nissan. Nonetheless, I'm going to call another time tomorrow now that I've had another 5-star battery test (my 6th
I have one good contact from LAB - will try reaching out and seeing what happens should my phone calls fail to make progress tomorrow.
