No new near-hit. High GPU prices are hurting innocent DC-project! The humanity!

As Michael already asked, what specifically is the damage they cause to the project? The only thing is a small additional load on the BOINC server.

I can see how it's irksome, but it doesn't slow down progression at all. Btw, if you want to get annoyed have a look at the oldest unfinished SoB WU, it's from last summer and it seems another user that doesn't finish tasks picked it up. ;)

Yes, it's only the ETA based on last week's numbers. I clarified that in the stats.

Update 17-01-2022

6) Message boards : Project Staging Area : New Factorial prime (Message 153194)
Posted 219 days ago by Profile BurProject donor
I'm not sure if it's in some way "unfair" or not. One thing would be that his negative results aren't published whereas PRPnet's are. But unless he has serious computational power the few negatives he produces wouldn't have helped PRPnet that much.

If he works fully independent, I'd have no problem, after all nobody owns Factorials, but if he uses PRPnet to some extent - and him being that close to the edge make it seem like it - that would be like poaching. Does anyone know if he's involved somewhere like Mersenneforum?

When I saw this I was excited at first, but seeing how it's that close to PRPnet's wavefront makes me a bit suspicious...

Of course Factorial primes aren't exclusive to PRPnet, but it still makes a not-so-good impression.

Things are still slow, last week's average is 9400 completed tasks/day. Due to DC that corresponds to 14E16 numbers checked / day. At that rate it'll be 582 days to complete the project. I added that to the stats.

Last update ist two weeks back, so mind that when looking at the differences. And we reached 1e19. Only 8 quintillion numbers left!

Tests upper bound: 10.1E18 / 18E18 (55 %, +1 %) Number of near-WW found: 310 (+-2) Distribution: |A|<= | Actual | Expected | Deviation -------|--------|----------|----------- 1000 | 310 | - | - 100 | 34 | 31 | +10 % 10 | 2 | 3 | -33 % 0 | 0 | 0 | 0 % Based on the current number of near-WW found, the probability for a WW prime is: 16 % (+ 1%).

First LLR turquoise!

I'll keep going though until I finally find a Proth prime. It's expected to happen once in about 30,000 tests and I'm at 24,500 which corresponds to 3 weeks of additional work.
