I wrote and rewrote that, and it still came out confusing. Let me try again:

After 5 miles of driving and building up an average, then I have this stop and an acceleration. The faster accel drops the average more, but arrives at speed sooner. Once arriving at the point where the slower accel would have been up to speed (200 yards farther along), the average is still lower than the slow acceleration would yield at that same point.

But I want to test some more to be sure...
