Why are we double checking these particular WUs (e.g. 334250016) please?

Because we have a long-standing agreement with prothsearch.com to double check all candidates.

Thanks Jim. The page you pointed me at says...
...PrimeGrid will reserve large ranges of k and n. It will perform both a first test and a double-check of all candidates.
How does that work with AR - do we not let on to them about that feature of our testing?
If PG are first and dc then why isn't the first host shown?
Are we running double checks on candidates outside of our reserved range to help out or something?

I'm not trying to be awkward I just don't understand, sorry.

I didn't read it closely enough. As per Lennart:

This is an agreement with ProthSearch to double check all ranges on all k's 3-1199

Some ranges are reserved by Primegrid and we do both initial test and double check. For ranges reserved by others, we perform a double check after the range has been completed by that other person.

Thanks again, that makes perfect sense.
It is a little annoying that we have very little chance of finding primes on those WUs though.
If it was found to be prime by the initial finder we would miss out and only if the initial test had incorrectly shown it as non-prime and we found it to be a prime would we get an elusive prime against our name. I suspect that we have never found a prime this way. Therefore I'd rather not be spending my time on WUs that have an extremely low chance of being a prime - but we have committed to do this work so I have no choice (other than to move to a different sub-project I guess?)

And what about hosts like mine that are, at the moment, subject to AR. The WUs I get as initial tester currently show a minimum quorum of 1 so they aren't being double checked by anyone? Is the statement on Ray and Mark's site just plain wrong?

Kind Regards.
