Questions on the Newsome 4yrd Box Pleat or 8yrd Knife Pleat?

[M. A. C. Newsome]

...I suspect that Scottish aversion to box pleats may be, rather, a vast Victorian conspiracy!

Or not. All of the kilts in Kenneth MacLeay's Highlanders of Scotland series of watercolors commissioned by Queen Victoria herself were box pleated (though made with closer to 5 or 5.5 yards).
