What is the proper way to break in rings

The Pro Stock guys break'em in on an engine dyno at full song!
The way to break-in rings for me was to put the thing on the track. 4200 rpm and a transbrake! At about 750 feet you could feel the engine seal up and start pulling better.
My way of thinking was that I was gonna re-ring the monster yearly regardless, so run the snot out of it! I never had a problem with my own or my partners 500" dragster motor.
