Fourth bar finally dropped on the way home after running some errands. Plugged it in to charge and then took a reading. Appointment to start warranty replacement scheduled for 17 October 2017.
The vehicle was manufactured in January 2013, spent it first two years in Georgia, was auctioned after lease return and brought to Las Vegas. I got it in March 2015. It dropped the first bar in October 2015, the second bar in June 2016, the third bar in November 2016, and the fourth bar in October 2017.

How often do you recharge ? By your data it looks improbably frequent.
By the way, I graphed your data. No obvious rhyme or reason to when you lost capacity
I have it set to charge every day, but it is on a timer, so it counts once when plugged in and once again when the charging timer activates (even if the battery doesn't need charged).
The vehicle was made in January 2013, so the cells inside the battery are the 2012 chemistry. The change in environment, bringing it to Las Vegas, accelerated the degradation. There appears to be a distance component to the bar dropping algorithm in the Leaf. I drove it a lot during the first two years, and not as much this year, which seems to have delayed the drop. I expected it to happen months ago, and it may have, if I had been driving it more.
