This is expected, since the computation of Sa takes into account much more data than the cross sections used to compute Ra, which increases the probability of finding outliers.

It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short-…
