stretching wire -- an anecdotal analysis

Which is why that early on during the chipping process
I use parallel pliers to squeeze the coil and continue to
apply that force while rotating them counter-clockwise
to advance this slackening in the wire.  It does allow for
a more stable pitch retention, it's an adjunct to reducing
the natural curve at other termination points.
