a slight summary...
Avoid cruising or staying at a steady rpm as much as you can... there's less tension on the rings and can lead to glazing in the bores.
Try not to clutch in while slowing down.. The key is engine braking, decelerating in gear. This provides high vacuum and gives the rings tension... Same with accelerating quickly.
Everything is wearing in, coatings are being worn off, so there is lots of particulate in the oil... lots of sustained high rpms creates heat, and can bake particulate into rotation surfaces, creating gouging or scratches.. not good.
An inertia dyno is super helpful in breaking in obviously, as you can use the drum inertia for sustained engine braking between ramp ups... hub dyno's, and small roller dyno's don't help with engine braking so just focus on the ramp ups.. In my experience, a dyno is the safer choice, and quicker for break-in, as you have more control, with the added benefit that you can dial in your tune at the same time.
Personally, I try to stay away from high boost during initial break in, to ensure the fueling is spot on and not washing the bores from over-rich conditions.
Take with a grain of salt... just my personal observations and experience
