I'm not an expert, just telling you what I've heard. Varying the throttle helps to seat the rings better from what I'm told. Non- detergent oils have less slippery additives in them allowing more friction between the cylinder walls and rings for better seating.

Then there are those that use synthetic oils for breaking in engines and swear by it. I guess it depends on the rings used and the hone pattern and coarseness.
