Well do the maths yourself, given a 0.010" (0.25mm) blade, and AR 4.7 rings from 1.6mm wire. Such a ring has an inner circumference of 23.6mm - so the circumference loss by sawcutting is already more than a percent. If you start with thinner wire, that percentage increases, and even selection of thinner saw blades can push that only a bit below a percent.

Given the inability to bend rings closed evenly around the complete circumference to bring the cut ends together when weaving, but usually only a small section of the rings gets the additional needed bend, this alone leads to ring shape uniformity variations in that one percent magnitude; so even a VERY experienced mailler won't be able to undercut around a percent with sawcut rings, consistently - typical is more likely around 2-3%.

And so even machinecut rings that haven't that diameter loss problem, can result in more consistent maille! Astonishing, yes?

Human societies are like chain mail.
A single link will be worth nothing.
A chain is of use, but will break at the weakest link.
A weak weave will have the need to replace weak links.
A strong weave will survive even with weak links included.

Astonishing indeed. I use a 0.008" inch blade, but that is really rather here nor there. There is still a loss. ...and then there is some variation in the springback from wire tension when winding. Possibly small, but I would think that would still figure into it. Especially for those like me who still haven't gotten a hands-free setup. (Yes, yes, I know...not safe. Still working on it!)
