Welcome Aboard, Yootsvik! That will be interesting to see if your 31.9 Ah figure changes after a long-delayed calibration cycle. My car with similar mileage only rose from 28.9 Ah to 29.1 Ah 5000 miles after transitioning from careful grandma thriving to hellion granddaughter driving, but suffice it to say, these cars and their battery packs appreciate exercise!
