Web interface, app v5.0.9 (3024).
Car: 2022 Tesla Model S with 11% battery degradation.
First leg on the route is 222 miles long, and the arrival SOC is predicted as 65%, when starting with 90%. Maybe some future Tesla will drive 222 miles and only use 25% of the battery, but that is not where we are today.
The results are the same using the iPhone app.
