What were your average speeds? We did a road trip and see closer to 300-310 Wh/mi when going 80-85 mph for long stretches (LR w/ Inductions).
I have TACC set to 8% over posted limits. That's usually about 6 to 7 over. Having owned 3 Volt's since March 2012 I have learned SPEED KILL's an EV's range and truth be told, the speed demons seldom really get to their destination much faster since they usually consume more energy and need to spend more time replacing it at the next charging stop.

The other thing, we are 68 years old and need to stop for BIO breaks well before the car needs a charge so whenever one of us need to stop (regardless of SoC) we stop at a SC'er and in that 10 or 15 minutes we add another 75 to 100 miles and NEVER have to worry about our wh/mi etc. I do think with EV's SLOWER can be FASTER.
 
Here's my teslafi report for my NY-Maine trip last week.

I think the main difference between these trip and mine is that I did not go on highways (rarely) and kept the speed down. This was a sightseeing trip, not a "get there trip"

Well that certainly looks like a lovely trip! I'll be heading from Maryland to Belgrade Lakes, Maine (near Augusta) in two weeks, but sadly mine is a "get-there" trip. OTOH, it's mainly along I-95, which has built-in speed limiting* in various places.

*Traffic and/or construction
 
Going from San Diego to Dallas (and vice-versa) means that you'll most likely be driving above 55 mph (max speed limit of 75 MPH in AZ/NM/TX) so your Wh/mile will be much more than 250. We just completed a short trip to Bisbee AZ from the SF bay area and our average Wh/mile was 353 in a 2018 M3P with 18" wheels and winter tires. Fierce winds and keeping warm will definitely lower your efficiency.
