I didn't check my m/kWh. My driving was atypical - highway speeds with the cabin heat turned on in order to run down the battery faster. How would it help to record my m/kWh? I could run the test again over the next week or so driving as I normally do and record it if I know how to use it. Thanks

New Battery capacity check using OBD-2
I got a new battery in my 2017 Bolt 4 days ago and did my first capacity check using OBD-2 codes from Sean Graham (thank you Sean). I'm wondering if this looks reasonable and whether I did the test correctly. Here are what I think the critical codes are at 100%, 50%, and 10% SoC:

The kWh used values come from the infotainment screen. My calculations estimate the capacity between 58 - 62 kWh with the battery temp in the mid 50s F. If 70 F yields the highest capacity, and according to Sean's FAQ the capacity drops about 1% per 2 F below 70 F, I need to add about 7% to get the capacity under ideal conditions. Assuming the kWh at 10% SoC is more accurate, then the capacity should be around 62 kWh (58 kWh X 1.07%). Does this all make sense? Thanks in advance.
