Task is past the 2 day mark. Hope it's a prime and not some kind of error. The progress % hasn't moved in awhile

I was just looking through my list of "all this persons primes" on the top 5000 primes page. Couldn't believe the smallest one that I ever got on the list 5 years ago this month is now 26,329th on the list. 22467261 · 2333333 - 1 100,351 digits.
Anyone have something smaller than that make the list?

Congrats TroubledBunny
I"ll also get my TRP gold today. This has been a focus project for me since I was in the top 15-20 on the old rs project before it went boinc. Hopefully we will blow thru this dc real fast.
PPSE - looks like it's been loaded with some higher-n PPS - does that mean that the smaller-n are finished?
I think its just that port. I also like the testing time of these tests vs some of the really long tests that could produce a megaprime.

I have a stupid question.
Found my first prime that entered in the top 500. What port was it from? 487*2^1005892+1
302,807 digits!!
[quote]They do keep lists of top x of specific types even below position 5000
PPS does have the possibility to find a rare Top 20 Prime Fermat Divisor.
