The first recorded twenty-two and a half hours of work at two competitions by four archers of the French national team, two of them in the world's top eight, and their coach: the archers work mostly on their own and seek out the coach when a drop in score persists, and even then they keep only the useful part of the advice; the coach watches, follows the scores and does not disturb an archer who is shooting well, and steps in on his own initiative only when he sees an archer who cannot handle an emotional reaction alone. The second, interviews with eight archers from the South Korean Olympic squad, confirms the negative side: a coach who dwells on mistakes during competition, or tries to correct the performance in the middle of a match, makes the archer more nervous, and the coach's anxiety spreads. The same accounts, though, include an archer who benefited from an unrequested intervention, a calm word and a clear description of his best shot straight after a seven, and another who complained of getting no useful guidance. What the Korean archers ask for, then, looks like intervention that fits the moment, not necessarily rare or on request, and on this point the two studies do not say the same thing. Everything rests on the accounts of twelve athletes and the observation of a single coach, and nobody has measured the score: that is why the status is "Contested".claim:allenatore-interviene-poco:revision:2026-07-15:2Wed, 15 Jul 2026 08:00:00 GMT https://matteocampagna.com/en/registry/competition/coach-intervenes-little-in-competitionclaim:allenatore-interviene-poco:new_claim:2026-06-24:contestatoWed, 24 Jun 2026 08:00:00 GMT
