"successes" in DC rankings?
This is probably a stupid question, but what is a "success" supposed to mean, in the context of doublechecking?
For example, the rankings page shows that I have 6 "successes" out of 7 attempts. At first, I thought the difference was due to incorrect results. However, all of the seven double checks I have done over the last year have matching residues. I am a bit confused.

A success is a matching residue at the time you submit the result

This is actually pretty simple: No matter what the work type, a "success" is a result which saves any further work on the exponent  proving it prime or not prime (by matching residues or finding a factor).
ECMF is a bit special in that even if we find a factor we continue to search for more of them, since the goal is to fully factor the numbers (isn't it?).

I was speaking only in the context of PrimeNet. Prime verification is a manual effort done using different software, like you said.
Similarly, finding a factor (by whatever method) will remove an exponent from the assignment pool, except for Fermat numbers. You can go hunting for further factors on Mersenne numbers (again, by whatever method), but you will have to manually assemble a worktodo file  those exponents won't be handed out automatically and are not available via the Manual Assignments form either.

Thanks, George. That clears things up.
