That's pretty good. We'll say (200+320)/2 for a 260 average.
My last 10 fills:
Most of my driving is in and around Bangkok, so don't eat at pumps and almost never use the bathroom at a pump. It takes 5-10 minutes to fuel, and I generally do not get out of the vehicle.
So, you have to make almost three times as often as I do and spend almost seventy minutes to do what it takes me less than ten minutes to do. This does not include the time into and out of the pump.
It does get better for you driving around town, as you get to plug in at home, but still the savings is minimal. I'm glad you like your EV, I think they're great, but I think the economic and environmental benefit are greatly exaggerated.
