Break-in

Hey guys, I'm taking delivery of my new Z4 in 2 days (pix coming!) Question about break-in...I know that you're supposed to drive the car at varying speeds and rpm's during this period, but how frequently do you have to do this while driving?
I guess the idea is to have the rings burnish the cylinder walls by creating high pressure. Is this pressure created by accelerating in a higher gear at low rpm?
Any tips would be appreciated!
