I got back from a road trip yesterday, so my GOM was actually reading pretty accurately (fast charging doesn’t trigger the reset back to EPA range). I decided to set my home charge target below 80% as a test, since 80% is where the GOM seems to go non-linear on AC charging. I was going to set it to 75%, but that is not supported, it jumps from 80% to 70% when lowering the setting. After charging to 70% overnight, the GOM only reads 166 (compared to about 245 at 80%,) so it would appear that keeping the target % below 80% does prevent the reset of recent driving history and give you back a more accurate GOM. Since most days I don’t rack up a lot of miles, I plan to keep it this way and only charge higher when getting ready to leave on a trip.
