Who have the highest primary find / double check ratios on Primegrid? I currently have 12 primary finds versus 2 double checks, which seems rather high...

Anyone who participated extensively in PRPnet ports or PPSE while there was adaptive replication for it will have really high primary find ratios.

I think I win with my (1/0), though I suppose I'm beaten by anyone else with n/0 ratio, where n > 1.

I suppose I don't count, though, do I? :D

There are many fellow crunchers who have found primes but have DCed none.
The top one I could see is this: 213 to 0

Those are all early stages of PG.

One of my smallest primes from 2010 is 17,434 digits.
Today, such LLR test can be done in less one second.
I could literally perform a milion similar tests in one day!

Anyway, there is no way to beat such a ratio today.
