Excellent question. I've heard, that due to the incredibly tight tolerances and improvements in machining in the last 30, 20, even 10 years, that this is NOT necessary, and is just a carry over from years of practice. I'd like to hear from some of you guys that really know the answer to this. Is a "break-in" period really necessary any more, or not?
