Factor vs WU

[Death]

Just one question - how many WUs save us one founded factor?

[Mystwalker]

Each factor proves that a certain k/n pari can't be a prime. Thus, we save a whole PRP test (and possibly double checking tests, as a found factor is very easy to confirm) - unless a prime was found for that k and that n is lower than the n of the factor found...

thank you.

so we can assume 1 factor ~ 1 test.

In the short term that is mostly correct, yes.
