How to run-in a new/rebuilt engine - Team-BHP

Hi folks,
There are a lot of theories out there on what is the best way to run in a new/rebuilt engine. The most well known one is "for the first 3-5k kms shift well below the redline and don't take it past 80".
Also, running the car at varying speeds and rpm's is another accepted method, but even in this case, the idea is never to go near the redline.

So what is your theory, and how have you run-in your engine? I used a combination of the above 2 - no redlning, stay within 80 and as for the varying speeds - Calcutta traffic takes care of that for you!

But is this the best way? I did some hunting around and found this site, which has a compeltely radical view-point. Makes for an intersting read, and makes a lot of sense.
