It seems most of the guys publicly voicing their break in habits have been trying to follow the factory recommended 2000 mi protocol. I can't recall any posts about owners driving them really hard from the get-go to "seat the rings".
I will be driving mine very hard for the first 100 miles (with proper oil warm up) and then take it easy and drive normal. During that first 100 miles I will change the oil twice. I've done this on every car I've ever owned and they all test right at the highest stock reported HP for that model.
Perhaps some do it this way but are afraid to talk about it publicly in the forums?
