Didn't you hypothesize that all the break in occurs in the first 20 minutes?? 
I don't think anyone has proved that synthetic is "bad" one way or the other, given the number of high end cars that are factory filled with Syn juice. That, and the fact that crosshatching can often be seen on high mileage cylinder bores would leave the whole break-in theory in question.

Yes, but this is for the benefit of others. And, I said a high percentage occurs within the first 20 minutes.
