The reality check

What the machines actually did with 81, across every lottery this site holds a long record for.

Powerballpool stops at 69
UK Lottopool stops at 59
EuroMillionspool stops at 50

Set for Lifepool stops at 44

Across 1 lottery that holds an 81, its average deviation from expectation is +0.17σ. Statistically ordinary, everywhere. (4 of the games do not go that high.)

The one thing a belief about a number can measurably do is change how many people play it — and a jackpot shared more ways is worth less to each winner. That is the only real consequence, and it is arithmetic rather than folklore.
