Agreed to disagree
I see it primarily when breaking in brand new strings. I think its a variable of the new string being in flux. But who knows, there are so many variables. I'm kind of suprised.... I thought that it was just understood. Heck a guy even published and article about it? Just goes to show.
Regardless, for those who haven't made up an opinion, check and track your nocking point next time you break in a string. I think you might be suprised.
PS When I was using more brass nocking points, (and I felt like things were done settling in), I would throw a couple of knots of serving below and above my nock points. (Sort of low committal hybrid.) Seemed to work great. my two cents
