Everything depends on the driver, weather, temp, too many variables to go by someone’s attempt at hyper milling. These are simple electronic devices. One should, in the very near future, arrive at standard measures for the efficiency of the motor, the battery and the chassis (weight and aero) separately and combined.  Scientifically. 
I can pussyfoot my Turbo all day and get 27 to 29 mpg. Does that beat the epa estimate by 20%. Hell yes but I know when I really use it I get 15. Lol. 

The EPA test as an average speed of ~50mph (highway part).

 

These guys drove faster than that.

" We drove between 70 mph and 80 mph the vast majority of the time, but we did push the Taycan up over 100 mph a few times, we just couldn't help ourselves.  "

There are many examples out there where people report around 240miles. EPA numbers were very pessimistic it seems.
