For what you know, there's still a chance you "could" be hurting your car in the long run, correct?
The only thing that seems more "solid" to me is what a manufacturer recommends.... unless some other automotive engineer can speak to the pro's and con's of driving under or over 4k rpm for the first 1200 miles, I think (again this is just my opinion) the best thing to do would be to follow what Nissan recommends. Wouldn't some form of Longevity appeal to 90% of car owners?
Again, I respect your opinion and I see some of your points. We can respectfully agree to disagree on some points (not all). I'm cool with that.

Cool, a well thought-out response! I agree that following the manufacturers method is a solid method. You wont mess anything up. While I don't have concrete evidence to back up other methods (and never will, since that type of evidence is not practical to obtain), I have read enough posts/articles from engine builders to be at least partially convinced of the benefits of a harder break-in. That's why I do a half and half type thing.
It's not my goal to convince other people what to do. I'm just pointing out that there are some experienced engine builders/engineers with detailed explanations of why one way or the other is better. And they don't all agree with each other. The debate does not end at the owner's manual.
