Only got under 10% twice in the last 3 years, mainly due to temp and headwinds having a bigger effect than I expected on a climb up to Tahoe. I moved from the Bay to Tahoe (where it was in a heated garage and mainly used my 4x4 during the winter) to San Diego currently so it’s been pretty babied. Granted I didn’t have charging at home in the bay, but was also careful not to leave it over night with less than 60% charge.

I think a lot of it has to do with luck of the draw, but most tend to loss 10% in the first year then hang out there losing a 1% or so each following year.
