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

They both do but only when Mercury is aligned with Saturn.

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

PrimePages and the entire UT Martin website both appear to be down right now.

Another congrats to Ryan Propper for the new 69 prime: 69*2^15866556-1 (4,776,312 decimal digits).

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.
