I was trying to estimate the usable battery capacity by using the following formula : Q = ( Miles Driven + Remaining Miles ) / ( Average Mileage of trip x Percentage of charge at start of trip ) before the update. I was planing to use this to see if it would show the gradual loss of capacity of the battery. I wasn't expecting any result for at least a year or two.
Before the NTB11038 update I got an average Q of 22.15 KWh. After the update I get 20.3 KWh. Each value was calculated over 4 trips (same route, but different conditions (speed, traffic)). The value that seem to have changed is the remaining miles: it's lower than before by 7-9 miles over a 36 miles trip.
