I can't give you any info re the printing characteristics of the filament from BilbyCNC as I haven't fired up my printer as yet.

I was not making comment on the filament obtained from them. It was just that I noticed this difference in the values for the diameter that I was measuring, and formed the opinion that everyone had misinterpreted the shape of the filament. The calculations were done to show a commercial effect of that misinterpretation.
