Seems reasonable, 250 ish mile range on full.

Good points. I should have mentioned that my 10% winter range hit is with a garage kept car that is preconditioned before my commute.
10% is actually a very modest range hit as at lower temperatures every aspect of driving uses more energy. The rubber compound in the tires is stiffer, the battery is less efficient at converting stored energy into electrical power, the heat pump has to work harder. The tire pressure may have dropped with the lower temperatures unless you compensated by adding air to the tires. There is drive fluid inside the front and rear drive units that is like ATF fluid, that increases in viscosity at lower temperatures. The air is denser too. At highway speed, in colder weather, range loss could easily exceed 30% when compared with milder temperatures.
I don't think this reduces consumption, rather apparent consumption. The Wh/mi increases when the heat is on ONLY when the car is not in park. Because you have a warm car when you put it in drive, the Wh/mi reads lower after your trip.
Before you exit the Tesla vehicle open the Climate Control screen. Tap on After Exiting ON.
I've read about this drafting idea but no one really says what the distance is that you should do this. Obviously, too close and you take the risk of the car getting sandblasted. But I wonder what the optimal distance is, or the max distance where you can still get some positive effect...
I drive 27 miles each way and consuming 10 kWh of energy each way. With a 77 kWh total battery capacity I estimate a 100% range of 207 miles or so. So yeah similar to yours. Slightly higher than yours because I live in MA not MN and probably slightly warmer that where you are. Have had my car for a similar length of time.
