A shoulder plane trims waste from a shoulder so the joint seats cleanly. Shoulder Plane reads published research that tries to trim “waste” edges from a measured week—residual blocks after primary employment—without turning those edges into advice for any reader.
What the mouth can register
Diaries and labor modules that name activity codes, reference periods, and nonresponse help place how much edge time appears after the main cut. When secondary earnings are measured separately from residual time, that separation stays beside any cited figure.
What remains proud of the surface
Commute spillover, care work, and recovery often sit outside the trimmed edge. Two instruments can leave different waste depths for the same population. This desk does not convert an edge mark into a personal week plan. Corrections: support@shoulderplane.online.
