JRC was developed long ago - 1973. By now there are about 50 equations associated with JRC. But almost nobody uses 3D tilt tests, as intended. Why?

14 December 2017 0 3K Report

The 'standard' set of 10 JRC profiles, chosen from about 400 measurements on 130 joint profiles, are 2D and for guidance only. Of course subjective in nature when used for estimation. Why so few 3D tilt tests?
