[QUOTE=kracker;342139]It would be nice, if there was a graph for Dc and LL, along with P-1 in the monthly, weekly graphs, etc.:smile:[/QUOTE]

Sorry [URL="https://www.gpu72.com/graphs/lldc/year/"]this new graph[/URL] took seven months longer than promised (ironically, only took an hour to implement; needed to get away from "real work" for a little while)...

At the bottom of all the [URL="https://www.gpu72.com/reports/overall/graph/month/"]overall graphs pages[/URL].

Thank you! :smile: :bow:

EDIT: And I know you're the main in DC on that graph... :razz:

I just hit a dry spell; none of the 100 DC TF exponents I just finished testing a single factor between 68 and 71 bits. It seems luck wasn't on my side this time. :sad:

What ranges are those graphs for? Pulling data ~weekly from the Classic GIMPS status page[SIZE="2"][SUP]TM[/SUP][/SIZE], I have been seeing changes of ~100-150 per day for the TwoLL column and ~190->115 in the OneLL column.

The attached graph has the rate of change in #/day on the left, P90 years on right. The data are taken ~168 hours (plus minus 8 hours) apart.

This is quite a statistical anomalie, isn't it? Should have found 4.

Could it be that P1 found most of them?

It happens quite often: I have a boxxen doing 65->66 bits for 317-319M range, 1 factor out of 308 reported thus far, found after 249 unsuccessful attempts. I "should" have a good 4.7, but remember- probability has no memory...

Using LaurV's logic you are unlucky so you should stop doing any TF.:davieddy: While you have been unlucky the chance of not finding a single factor in 300 trials is ~1.3% if no P-1 is done and ~5% if P-1 is done. So it does happen once in a while.

no, it is just that the Luck is in my area now, and I did efforts to tie him on the tree in front of my window. I will release him now, so other poor guys can find some factors too, and so we won't lose them from the project... :smile:

If you want to find a lot of factors, head over to [URL="http://www.mersenne.ca/"]James' site[/URL] and do some trial factoring > 1000M. You will find a factor about every minute...though no credit is given for work less than 2[SUP]70[/SUP]

What is the odds for ten consecutive factorisations? I had the pleasure of experience it once when running the smallest unreserved candidates in 87M... :fusion:

Ps, I know the probabbility, somewhere close to 0.015^10 = 0.58*10^-20 so someone set me up or <deity> has a sick sense of humor.

The "phenomenon" is quite common, and it happens to any of us who do TF in bunch, at least is happening to me every time when I submit :smile:. It is due to the fact that - when you submit a long list of factorization results - the server (PrimeNet) is "sorting" the list, taking the NF results first, then it goes again through the list taking the F results second. Therefore, if you have 100 factors in your list, they will appear "consecutively" in your results report, but the exponents themselves are *[B]not[/B]* consecutive (look and see!). So, no magic.
