The hard part is the shape of the fall. In beginners the collapse is all in the first few yards: from ten to twenty yards they lose fifty-eight points on average, then about twenty for each further step. And in thirty club women the score over three arrows is higher at eighteen metres but identical at thirty and at fifty, that is, the fall stops. The likely reason comes from a figure about the format: at a fixed distance the score rises with the diameter of the face, from 7.7 points on the sixty centimetre face to 8.9 on the hundred. What counts is not distance itself but how large the target is as seen from the shooting line, and that is why seventy metres on the 122 and fifty on the eighty resemble one another.claim:punteggio-cala-con-distanza:revision:2026-09-30:2Wed, 30 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/competition/scores-fall-with-distance#storiaThe first partly contrary figure, and the status falls. In thirty club women the score over three arrows is higher at eighteen metres, a median of 26 out of 30, but identical at thirty and at fifty metres, a median of 23 in both cases. The fall shows in the step from indoors to outdoors and then it stops. This is a single study, with three arrows per distance and scores reported as medians, so the claim goes back to reported and is to be read with that limit. The same year a scoring model estimates that twenty centimetres less raise the expected score over 72 arrows outdoors by 0.25 to 0.42 points, more for weaker archers: a calculation that points the way of the claim and does not affect the status.claim:punteggio-cala-con-distanza:history_entry:2026-09-17:2019Thu, 17 Sep 2026 08:00:00 GMT https://matteocampagna.com/en/registry/competition/scores-fall-with-distanceclaim:punteggio-cala-con-distanza:new_claim:2026-08-18:riportatoTue, 18 Aug 2026 08:00:00 GMT
