I'd want to look at his reasoning, if available. Because this outcome can happen through ordinary chance.
From a probability calculator:

If my actual skill level is 55%, then my chance of achieving 66%+ in 100 trials is almost 2%.
If I'm applying this correctly, then a 60-entrant contest should produce one 66%+ outcome despite everyone being only 55% skilled.
If I'm totally unskilled (50%), then I'm only 0.1% to achieve 66%+. But a contest of >1000 unskilled entrants should produce at least one such outlier.
