The best-fit filter rejected pairs over a 5:1 aspect (or the plate's) unless 75% utilized. A long part such as U251-DET3 (27.4 x 3.5, aspect 7.7) is past that alone, so its tightest interlocked pairs (5.1:1) were all dropped even though they are less elongated than the part itself. On the 60 x 120 sheet that cost 12 parts: 66 placed instead of 78. The limit now widens to the part's own bounding-box aspect, so side-by-side pairs survive while end-to-end pairs of compact parts are still rejected. The learned-angle characterization nests re-captured: their 46 x 3 bar now nests as an interlocked pair, which left the Fill nest identical to a full sweep, so the notched quantity drops from 6 to 4 to keep the fixture sensitive to learned angles.
