Lots of factors, but ABRP is very conservative..needs to be to keep people out of trouble. But in the past month I made 2 identical 125 mile round trips, starting at 4300 ft, going to 7000 ft and back...all highway, avg speed 75. Avg temp ranged 75-80, AC on but not working hard. Charged to 100% and Reset mi/kWh before starting. At the end it showed 3.8mi/kWh. Used just less than half battery(66kWh)
Many other similar trips. In middle of winter its more like 3.2 mi/kWh. Worst was different 200 mile trip, on I-15, at 88mph avg in winter. Yeah, couldn't make it...had to DCFC. 2.5mi/kWh.
If the conditions were right I'd feel fine going 261 miles at 65mph, especially with a few L2 available(if needed) on the way as OP described.
