Super helpful. Similar to ICE, 55 definitely seems to be a sweet spot.
What does +/-Aero mean?
I have P+ as well and can confirm those numbers are pretty close to accurate. I typically cruise around 70 mph and could get around 260-270 miles of range when extrapolating.
"Aero" refers to the aerodynamic hub caps that are only available for the 18" wheels (stock option).
I agree with what others have said in suggesting a 120V trickle charge over night (~4-5 miles per hour of charge isn't shabby!) and/or a quick stop at a supercharger. If you visit a supercharger with under 50% battery (it charges fastest when you are low on battery) then you could get 100 miles of range in less than 15 minutes! You'd probably only need 50 or so max, so it'd be over pretty fast.
But be careful - with the P, if you drive aggressive you will eat battery real quick
