Shoulder

The curved stroke arching out of a stem, as in h, m and n.

Near it

what it is	the arch of an n, m or h, and the point where it leaves the stem
measured from the source	the arch leaves the stem at exactly half the way from the family's own x-height down to the baseline, on all eighteen families whose arch is drawn as its own stroke	read from the shelf's own stroke data on 2026-09-29, rather than measured off its ink, against each family's own x-height from the family engine. The arch is a separate stroke that starts ON the stem, so the joint is a coordinate somebody wrote rather than a curve anybody has to fit. CORRECTED 2026-09-24: this row said 0.425 to 0.567 with 13 families at half, measured against the BASE x-height for the eight families that move it; the family engine moves the joint with the line, so it stays at half. Outline and Engrave redraw the stroke as its edge, Extrude doubles it and Stencil and Perforate cut it, so their data holds no single joint to read
the two that are not two strokes	Drew Gazette and Drew Slab draw the n in six	their serifs are strokes too, so the count says as much about how a serif is made here as about the shoulder
