I've given up peering at the GOM. I know I'll get a guaranteed 130 miles from my SE driving with scant regard to efficiency and with a warm cabin, so I just keep the 'from last charge' setting displayed.
I'm usually around 15% at the 130 mile point and ready to charge.
It's a little disappointing TBH but it is cold and wet, this is not an efficient winter car though.
I'm guessing 150 miles in spring, up to 170 miles summer, but like I say, I do drive it with no real attempt for frugality, life's too short
