I think he might just have gotten tired of this or forgot-he was last online 10 days ago on mersenneforum.

long time no seen, pg :) crunching badges again now

Mmh, wafflingdwarf seems determined not to give up her/his #1 spot:

#2 ~ 56,022 tasks
#1 wafflingdwarf (57,198)

And the probabilities for wafflingdwarf (and me)

≥1 prime: 98.13% (97.97)
≥2 primes: 90.70% (90.07)
≥3 primes: 75.90% (74.66)
≥4 primes: 56.27% (54.65)

Or...they are determined to give you the first spot by getting a prime :D

I have done 515947 tasks with 35 primes (5 of those 2nds).
515947/30 = 17198

IMO, for the purpose of calculating (your) average tasks/prime you should treat initial prime finds and doublechecks equally.
So you're at 515947/35 ~ 14741 tasks/prime.
Which is pretty much where I'm estimating the overall average tasks/prime to be. I put it around 14370 (it ebbs and flows over time depending on how many primes have been discovered recently).
Of course average doesn't mean anything for the individual. I'm at ~ 3*average but alas ...

I wish you to find one soon!
It has to be soon!

Thank you. I've been telling myself the same for a while now and, as the saying goes, hope springs eternal. :)


I agree with Omega in terms of calculating the average tasks per prime. Good luck on prime-finding! It's always a wonderous moment to get your first...
The chances of you getting the PF vs a DC really depends on your computer, and in the case of roughly equivalent computing powers, the chances would be aruond 50%.

Well, well. I am out of that list before even getting into that list. Took me ~17600 tasks.

25 million. Didn't notice when lol probably mid-February.

Congrats !
According to https://stats.free-dc.org/stats.php?page=milestones&proj=pgrid&team=14:

that's awesome! thanks

But honestly, when was the last time you encountered something in life that had a 98% chance of occurring and yet it didn't?


not to be annoying, but trying to find an SGS

On a different note, AMD's mainstream desktop CPUs currently have up to 16 cores, Intel's high-end desktop CPUs, let alone workstation and server CPUs, can have even more cores, so there might already be several potential participants who exceed the 8-thread limit with all their competitive CPUs (I'm planning to join that group soon). A better idea than a limited number of cores might be to normalize the time by number of cores.


More cores usually mean more cache, so normalizing it would be harder since tasks would more easily fit in cache of say 12c CPUs than 4c/2c CPUs.

Unluckiest SGS crunchers (part 2):

Second table includes those who've found primes but have more tasks (in the current range) than expected (based on number of primes [incl. DC] found):



I think you could also rank them by percentage skewed instead of just nominal difference of tasks, would that be clearer?

2M~

3 million now! After half a year.

4 million! After a month.

5 million! After 11 days. And first time RAC above 100k!

6 million! After 16 days. Doing short tasks with no bonus.

7 million. After some 25 days.

8 million. 26 days, more badges.

9 million. 11 days. Almost broke record.

I have passed 10 million!!! 7 days since last update.

15 million. 76 days if my calculations aren't mistaken.
Last time was 85 days. I guess that's a record :)

20 million! 65 days.


25 million. Didn't notice when lol probably mid-February.
