The purpose of the break in is to give the new parts (that do not fit perfectly together) the opportunity to mold together. IE. you want the rings to mold to the cylinder wall. If you bust into it straight out you could actually score the cylinder wall to match the ring instead. Same with crank bearings, cam bearings and many other parts. It just gives everything a chance to set together.

I'll take your insults as compliments and blame it on your lack of intelligence.
