Initial starting does play its role, but the benifits are still available for a few heat and load cycles even if the car has a couple of km on it.
From picking the brains of engine builders over the years I've learnt you need the engine at operating temps and under full load, before too many heat cycles and/or km.
I acknowledge this is a "can of worms" topic, I'm only putting forward what I have learned and what processes I use to break in a new engine using, what I believe are, sound engineering principles.
I've used this method on all new vehicles I have purchased and any engines that I have had built for me, cars and bikes included.
I'm no engine builder or mechanical engineer, but to me, the proof is in the pudding.
