I'm a big believer in the rev-up-coast-down-avoid-constant-speeds method (which, BTW, is not inconsistent with the Nissan recommendation...), although my explanation for it (heat cyclying) has been debunked...
Anyway, zero oil consumption.
I've broken in two motors this way and had no issues with either, so will continue to do so until I see compelling evidence pointing to an alternate method.
The idea of the method I use is to neither baby it nor drive it like you stole it, but rather to drive it "normally" and avoid constant engine speeds whenever possible.
