Just for the record, my 32 mile a day commute has done a recal everyday this week, but for the first time did two today, and interestingly after the second recal the battery gauge only went up to 10 bars, where it was always charging up to and hovering around the top 4 or 5 before. But for the first time this week autostop didnt play up.
I guess the patterns of deterioration will vary with type of journeys made by people. My commute is quite hilly, so I get good charges down hill, but unfortunately not the assist I expect on the way back up. Im still managing 68 mpg average, where on this route in the one week I used the car in October, it was 73mpg. Perhaps a little indication of the IMAs fuel saving capability, but it could well be colder here atm too?
All this battery funny goings on makes my dull commute that much more interesting
