BS, MS in Mechanical Engineering and PhD in Applied Physics. I have over 25 years as a design engineer and I DO have a significant amount of input into the manuals that are written for the devices that I design.

For the halibut, I'll pass along what my salesperson said today when I asked him the break-in question. "Drive it like you stole it!", he replied, "Just make sure you vary the speed early on".
Oh, and I wish Texas911 was a tad more civil in his posts or that he would start taking his medication(s) again.

IMHO:
The mileage seems ridiculous all alone. If you baby your engine for 2000 miles below 4200 RPM I would bet it is not really properly broken in. To make it worse lets say you did it mostly in 6th gear on the interstate. Then, at that point if you suddenly beat on it, that has got to be a bad thing.
On the other hand if you are running around some tight canyon roads the same number of total engine revolutions would be reached with a lot lower number of miles. I don't think sooner or later is nearly as important as gradual, varied and controlled. The advice cited in the other posts above is logical.
Just think how she would want to be treated if she were a woman. Tease her for a month and then slam her up aginst a wall? Probably not.
I think the most conservative thing would be to follow the manual and then one of the above procedures. Honestly though I'm not sure the first 2k easy miles isn't just a lawyer thing to keep posers out of the weeds.

Many of the sites quoted above say to use dino oil, not synthetic for break-in. One also said that if your car came with synthetic oil from the factory, that the factory took care of the initial break-in.
Porsche used to run all 911 motors on a test bench before installing them in the car. Do they still do that? They also drive all new cars on the Autobahn as well. If so, could they do the initial ring seating there?
Can't you do the break-in while still observing the 4200 limit (or a bit higher occasionally)? To avoid lugging, it is a short rpm band, but it can be done.
This is no longer theoretical for me, as I expect to pick up the new car the week after Thanksgiving.
