Hey first off thanks or posting the details so often. I am actually amazed you stuck with the car for so long. Kudos.
I am not sure but it looks like you got your new battery at about 73k miles and now you are at 116k, so you lost the bar (~15%) after 43k miles ; 15%/43k = 3.4% per 10k miles, which sounds really good for these cars. My 2015 is at 13%/35k = 3.7% per 10k.
2015 Leaf S. Red. 34K+ miles.
