I have seen american V8s torn apart with 1500 easy miles and ridden hard with 1500 miles, the rings seat lower in the easy break in and when you ring it's neck the rings smack the lower"slow break in" seats in the cylnder walls resulting in lower power. I do not know if this applys in these modern tite clearance engines.
