All, sorry if this should be posted elsewhere, but I can't find anything in my searches.
I keep a detailed account spreadsheet of my daily commute to determine optimal charging levels, etc. vs charging at work. In doing so and through use of details from My Leaf app I am running into a discerpancy I would like your feedback on:
2 days ago: 20 mile commute, Percentage charge used 15% (58 down to 43%), computer says 3.8mi/kwh and 5.33kWh total consumption
Today: 20 miles commute, Percentage charge used 18% (52 down to 34%), computer says 4.4mi/kWh and 4.67kWh total consumption
Both commutes under similar temperature and driving styles, no changes. So how can a more efficient drive (today) of 4.4 use more percentage charge than a less efficient (2 days ago) drive of 3.8?? Is this a computational problem somewhere in the app? All the other numbers besides percentage charge make sense to me. How can a more efficient drive today use more charge?
