We talk so often about swing speed with the driver that we underestimate the two setup screws that really deliver σ-consistency: the drooping right shoulder and one stable body axis. Both are not power topics — they are pure mechanics topics, and they also work at 75-90 mph senior swing speed.
For me, this exact setup adjustment has cut my dispersion in half over the past few weeks: σ length 8.1 m, σ width 8.9 m (previously: 17 m). The path improved from −8° to −3.6°. This is a fairway-hitting lever, not a distance lever. But: 5 more % FiRs are statistically worth 1–2 strokes per 9 holes—much more than 10 m more carry.
