Someone (I don't know their username) emailed in a suggestion to add counts to the discoveries links on each user home page.

That's done, and if you look at your user page (or anyone else's), instead of "primes, APs" you'll now see something like "primes (8/7), APs (248/91)". The numbers in parenthesis are the number of discoveries and the number of double checks.

For some people, like me, you'll notice a lot fewer AP double checks than discoveries. It's even more noticable if you look at Lennart: He's the one with 614 AP discoveries without a single double check.

No, there's no super-special strategy for being first. The original AP26 search didn't use double checking, so there were no double checkers at all. Likewise, a lot of primes were found on PRPNet, which doesn't have double checking.

When you look at the accounts of people who have been here for a while, you're going to see that their number of discoveries may be much higher than their number of double checks. It's not because they have a secret method to always be 1st. It's because back then, there was no such thing as 2nd on many of the projects.

Hm, did those ranges ever get double-checked? What are the chances we missed an AP27 or AP28?

Yes, and therefore zero.

The new AP27 search intentionally was set up to start by having some of the search double checking the old AP26 search. The following ASCII graph illustrates the new vs. old search. The vertical axis is k, starting at the top and going down, while the horizontal access is the shift, in 64 bit increments. The blocks of 10 shifts (640 bits) are the shifts used in the new ap27 app.

......xxxx xxxxxxxxxx xxxxxxxxxx ....xxxxxx xxxxxxxxxx xxxxxxxxxx ...xxxxxxx xxxxxxxxxx ..xxxxxxxx xxxxxxxxxx .xxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx xxxxxxxxxx


"." represents the original AP26 search, which was also double checked by AP27. "x" represents the new AP27 search, beyond the limits reached by the original search.
