You don't actually say how many miles 'in 4 months' were done.
If the SOH was right at the bottom of the 12th bar on purchase, and the BMS was being a bit, say 2%, optimistic in the warm weather in July and dropped into the 11th the next day, dropped down to 10th (6%) and onto 9th (6%), so that is 10%. Possibly the BMS is being a bit pessimistic now, say 2%, in the cold, so that'd be an 8% loss overall.
....Not saying 'is', just saying 'if'....
Nissan guarantee of 30% loss over 60,000 miles, so 8% equals guarantee loss might be expected in 16,000 miles.
Or say 1 in 4 people lose their first bar (15% loss) in av 15,000 miles, so 1 in 4 experience an initial 1% loss per 1,000 miles.
8% loss (which could be 3 battery bars in certain circumstances) could be experienced by 1 in 4 unlucky people over just 8,000 miles.
