Model S 75D Indicating Max Range of 310 rather than 259 Miles

[M-Polo]

I have a new Model S 75D (800 miles). I was supercharging today and suddenly the mileage range jumped from a max of about 260 to a max of about 310. This is clearly incorrect, and the battery percentage continues to decline at a rate consistent with a 260 mile max range. Nevertheless, rebooting the software did not change the indicator, and Tesla has been unable to resolve so far. Anybody else have this issue?

Do you accidentally have the mileage set to display in “ideal” range?

Congratulations, your Model S 75D has transformed into a Model 3 Long Range!
