On the platform the left foot sways more both sideways (p = 0.027) and forwards and back (p = 0.001), and the overall centre of pressure sways more forwards and back (p = 0.017) but not sideways, while the right foot does not change. The result therefore points two ways, more sway on the left foot and no change on the right, and that is why the status is contested. The weight of the evidence is small in any case: the poster does not say how many archers it measured, publishes neither means nor effect sizes, compares two measurements on the same archers with an independent-samples test and does not record the score. Whether that extra sway costs points, then, nobody has yet seen.claim:pedana-finali-oscillazione:revision:2026-03-03:2Tue, 03 Mar 2026 08:00:00 GMT https://matteocampagna.com/en/registry/competition/finals-platform-postural-swayclaim:pedana-finali-oscillazione:new_claim:2026-02-02:contestatoMon, 02 Feb 2026 08:00:00 GMT
