"the statistical math" supports no such claim. Perhaps, numerology or palmistry does.

It looks like there is a conjunction with a second 69 prime

 2021-08-31, 12:28 #74 diep     Sep 2006 The Netherlands 2×17×23 Posts Yes much congrats. It's delivering less primes than i would've expected. Last 6 primes projected after the 3.14m i found then on average each new prime is factor 1.3 further away. That is pretty bad and way way less primes than i would've expected.
