Hi All,

I'm doing some investigative programming. I'm measuring a machined 30mm (-0/+.021mm) bore as a cylinder __twice__ in my program using the same amount of points each, once using the Least squares algorithm, and once using the max inscribed algorithm, to see what kind of differences I see. There are a couple occasions when the least squares actually comes out .001-.002mm SMALLER than the max inscribed. I've always assumed the max inscribed would always be smaller.

Can anyone point to a scenario where the least squares would actually be smaller?
