EV efficiency fudge factor

it would be great if there was a button at the end of your drive that said: “how did we do?” And allows you to enter in the destination charge level. That data could then be used to update a fudge factor (maybe the speed coefficient?) for your vehicle such that the next trip is more accurate and a more reliable predictor of charge.

Ie- if the projection said I’d start at 100% and end at 20% but I actually sensed up at 5%, you adjust the efficiency by entering the actual destination charge level (5%) which updates your vehicle settings and the app gets better over time.
