Least miles to a full charge?

[Subevo]

charged car to 90% on a model s 75D. Bearing in mind average temp about -3. So far done 20 miles and now at 60% lots of preheating and short journeys over several days.at this rate I will be lucky to get 60 miles. It got me wondering if anyone can get worse than me.

I’m sure it would be possible to do worse, but however bad the Wh/m I’d be plugging in every night anyway. That way at least the morning preheat is using shore power and I’d be starting with a full tank.
