Going 65 mph you passed by lots of traffic in Texas? Were you taking some back-roads route rather than the e-way?
No, no. Lots of traffic went flying by me. Only passed a few slow moving trucks.
Were those figures provided by the vehicle trip computer or did you calculate them based on miles traveled and fuel consumed? Were any adjustments made to correct for any battery capacity that may have been used during the trip?
The figures were NOT from the GOM or trip computer. Miles traveled was off the odometer (zeroed trip computer). Started each segment with a full fuel tank and immediately refilled at the end. HV was immediately activated at start and on any stops, so no didn't try to correct for any battery usage. Was depending on the software to maintain the battery SOC setpoint.
As you have observed, you can magically lose a bar or so, or some EV estimated miles on long trips especially on stops. I once. near home, running as an EV stopped at the local convenience store. Estimated EV miles was 2.3. When I came back out and restarted the EV miles was 0.0. Where those electrons magically disappeared to was a puzzle.
So no, there was no adjustment for any battery SOC changes. Pretty minimal at best.
