Agree that it is still pessimistic, but as a guideline it is certainly "good enough". I'll contrast your experience with my trip from flat southern NJ to the pocono mountains and back; It was off by about 15% after the roundtrip, but that is a reasonable cushion for me. Had it been raining or some unforeseen detour, then there would have been no cushion. I am perfectly happy arriving at a charger with 10% or 15% more in the battery than projected; I'll still plug in and charge to the target while also taking the planned break. If it gets a little more because it charged faster than it took for the bio break I am OK with that. I am by nature a pessimist, so things taking less time than expected is OK with me.I went into ABRP and put in a trip Phoenix to Williams AZ. When I did that trip to Grand Canyon, that is where I charged, and arrived at 33% battery remaining. Speed limits are mostly 75 mph and elevation change is 6000 feet, uphill. To get ABRP to come close to the actual, I had to put in 4.6 mile/kwh reference at 65mph. As an engineer I know that is not a good reference, so it means that the drag and elevation equations are way off in ABRP.
