Nope. The buffer is always included. It will be 70.2 kWh when full, 37.3 kWh when at 50% and probably around 4 kWh when 0% and will continue to decrease to 0 kWh as you drive below 0% battery.Fair enough.
So, in the first screenshot the buffer is included and in the other isn't?
If this is still confusing, think of it this way: the battery level doesn't mean anything unless you're at 100%. It is literally a fabrication. This is why you can keep driving below 0%. Empty is not really empty, half is not really half, etc.
