All tested compact sets round offsets to whole bps. The cost curve is steep below 13 knots: s-only falls from -0.319 at 13 to -0.828/-1.741 at 9/7 on tuning; averaging is not better. On 2048 holdout, s13 is -0.272 and avg13 -0.294, so neither reaches the -0.2 bar. Next try nonuniform knots concentrated near W2L's dense central region, or retain separate s/c only where their spread is material; do not ship this unqualified compression."}
