The theory is that giving the engine ~3/4 throttle pushes the rings against
the cylinders, helping them to seat; backing off the throttle creates
enough vacuum to pull oil back up to the rings for cooling/lubrication.
The best engine I've ever owned I broke in by taking a 2K trip through
rolling hills on a 2 lane road.
