Interesting. So you think there is an invisible chevron pattern below the surface, but you don't think annealing does anything. You been sharing one too many with Miller I think.
The “chevron pattern“ below the surface of the wire - the deformation of the copper atomic structure - would be damn hard to see unless you had Superman’s X-Ray vision. 👀 Furthermore the chevron pattern on the surface of the wire, if that’s even there, which I’m not sure it is, doesn’t necessarily mean anything. So, far we’re not anywhere closer to an explanation than when we started.
