I've followed this procedure (i.e., what is described by Nissan, other car manufacturers, and two engine builders whom I trust very much) for two different engines, and notwithstanding my flawed reasoning regarding the specific effects, it absolutely resulted in smooth running, non-oil burning, high power making motors.
Thanks for posting the detailed explanation of why the procedure works and glad to hear she is breaking in nicely 
I suspect the oil burning and the unusually high temps some folks see in normal driving are the result of poor break in. |
It may, or may not be a result of poor break-in proceedure. Breaking a car in properly just helps.
Yes, heat-cycling is a good thing. Don't just go on one 1200 mile trip.
However--this said--the Corvette Museum has people fly in from all over the US to DRIVE their cars home. They just recommend that they vary the rpms, take some back roads, row through the gears, and stop a bit to have lunch and then stop to see the sights, maybe. It is an exact science, but manufacturers know that most people are not exact scientist, and they planned for it as best as possible.
Regardless, that is how I break my cars in. My Z06 burned 1/2 quart in the first 500 miles, and not a drop afterward.
As to "allow for coast-down", I'm not following?
