Battery usage percentage sometimes is wrong
Today my last two drives are logged as:
1%, 0.93 kWh
2%, 0.92 kWh
I think it doesn't make sense that the first percentage is lower while the kWh are slightly higher.

How about now using Teslas battery percentage (which is heavily rounded as you state) but your own calculations based on the rated miles at 100% (individual car factor) and the rated miles used for this drive. Like you do for the kWh, if I got that correct.
This way the value would be more exact and would be in line with the kWh.

The battery percentage is rounded to a whole number somehow and has an accuracy of .9%. The kWh is calculated through rated miles used which has an accuracy of .1 miles and a scale of 200-300 miles. Plus the kWh used is rounded.
For example:
89.9% - 91.1% could be reported by the API as 89% - 91%. 1.2% really used - 2% reported by the api.
89.6% - 90.9% could be reported by the API as 89% - 90%. 1.3% really used - 1% reported by the api.
