measured on this shelf	the p's ink below the baseline, over the height of that face's x: 0.2009 on Drew Poster to 0.4248 on Drew Extrude, with Drew Hairline at 0.3000	measured over all 23 house families, Regular, on the fixed shelf, 2026-09-24. Pixel at 0.1802, the shallow pole this row carried, was measured on an earlier shelf; Extrude's 0.4248 is unchanged
shallow	Drew Poster at 0.2009
deep	Drew Extrude at 0.4248	Extrude draws the letter with the letter behind it, so part of that depth is the extrusion rather than the descender, which is why the number is given with the face named and not alone
