YES, the Trip A or B, if not reset, is calculated for the total until reset, or battery disconnected, would be stupid if it only calculated for previous 300 miles. See page 305 of owners manual, have to hit OK to reset
per the % highway, is primarily 25 to from work, and some short local trips around town on weekends. Evic has been +/- .5 relative hand calc at fill ups. Innaccuracy due to when shutting off the pump.
Worst mileage has been around 19 on first tank, but I was hammering it to seat the rings, best 24sh on 200 mile trip each way.
Point is it is beating the highway rating easily by over 10% with some local mixed in.
