What do you find unusual about the pattern? Is it the position of the knot for the cross strings?
If so that’s a new thing the yonex stringing team came up with not long ago. They tie the cross strings on a cross string instead of a main string. Apparently it helps reduce string breakage when you have thin cross strings and thicker mains at high tension. I think they originally discovered that for aerobite strings but there’s no reason not to do it on other strings really.
