I’ll echo what Andretex said.
Touring with 19” with aero caps removed 23K miles. My lifetime is 3.6 m/kWh. This translates to about 330 miles of total possible range. While I start at 100% on road trips, I never go below 15%, and I never charge above 80% once I’m on the road (charging is too slow after 80%). This gives about 215 miles max between stops which is plenty.
Most useful metric for me is 3 miles for every 1% of charge. This is a very conservative (safe) estimate. For instance, if I’m at 50% SOC, and I don’t want to go below 15%, I have 35% available which translates to at least 105 miles.
YMMV but probably not by much. Remember range worsens significantly if it’s very cold.
