I’m not allowed to use a ODB Dongle on my company car.
I found out that the Charge level Prediction is often of by +/-5 to +/-10 on a 80 to 30 stint.
Change the Battery Charge prediction display to a button where when you tab or better double tab on it, it opens a dialog where you can add or subtract 1 or 5 precent points of the batty charging state.
