This is why it might be easier to just say "all Mersenne numbers with less than ten million digits have been double-checked". This is not normally an issue for the XX million milestones, as "all exponents below XX million" also means "all exponents below or equal to XX million" simply because XX million will never be prime.

At one point, I had tried to make a graphical timeline of the milestones, but it got a little unwieldy. I still think that would be a cool way to visualize the different milestones, rather than a long, boring list. At the very least, the milestones should probably be separated into three lists: prime discoveries, first-time test milestones, and double-check milestones.

I'll have to do a little SQL magic to work out the actual date a single or double-check came in. The smaller exponents won't necessarily have that info in the v5 database either...maybe in the v4 database. :)

I do not believe v4 kept the dates; at least they were not imported into v5. I don't remember seeing dates in the database until v5 began beta-testing in mid-2008.

Thanks, that was good info.

The current database doesn't have date stamps for older results (pre-2007/2008'ish) so it's hard to nail the dates down.

I confirmed the missing double-check stats with the ones you had, plus a few more. I don't have any dates on older double-check milestones (3M, 7M, 11M and 12M).

I'll have to look through the single-check stats later and see if I can't fill in some of those... seems like I should be able to find them for 21M and up since those were all post-2007.

Not much I could do for the single-check milestones missing before that (3M, 7M, 11M, 13M, 14M, 18M and 19M).

The milestones don't always progress smoothly... there are several instances where one smaller exponent held up 2 or more 1M ranges because it was just so slow to finish. You noticed that when a <32M exponent checked in which officially finished everything up past 37M in one swell foop. There's always going to be those crazy outliers I guess.

EDIT: Okay, I verified your #'s and there were just a few minor corrections, just a day or two on a couple. You kept good records!

I was able to look back as far as the single-check milestone for 24M but further back than that takes us into 2008 which was in the midst of the v5 database update, so date stamps on results before then aren't available. Not bad though to go back that far.

I'll try and streamline the milestone page...at least make it easier by grouping the milestones into sections. Maybe graphing or something, but I don't know how useful that would be since any graph is going to be sporadic with one slow result holding up millions of milestones. :) Maybe over the course of 6-7 years you'd get an idea of the trend line... that graph a few posts up is probably the best you'd expect.

Okay... milestone page updated (for the "older / lower profile" stuff).

Rather than have it all together in one chronological lump of stew, I broke it into the single-check, double-check, and then the other miscellaneous stuff.

It has dates filled in for some of those older things, wherever possible. If anyone else out there on the interwebs happens to have dates for those other things that they happened to capture, I can incorporate them.

Ongoing, maybe it'll be good to put the latest n-millionth single/double-check milestones in that first section so they're more prominent, and then demote them to the older section when the next one is reached. Kind of been doing that, it seems, for the single-check milestones already, so nothing new there. I can start that with the double-checks when we hit 34M.

Hehe, "Double time checks". Sounds like a musical beat rate measurement.

And we can add "Countdown to double checking all exponents below 34M: xx" and automatically bump it up to the next million as each milestone is reached.

I know it is redundant information but maybe add this line to the misc section?:

2010-12-25 All exponents up to 33,219,253 (10 million digits) tested at least once.


Maybe change the million digit to similar text to the 10M digit:
1998-12-26 All exponents up to 3,321,917 (1 million digits) tested at least once.

and you could also add this approximate milestone:
2001-Feb/Mar All exponents up to 3,321,917 (1 million digits) double-checked.

Based on the status file information I had (unless you can see more on the server):
January 28th, 2001: All exponents below 3,210,800 have been tested and double-checked.
March 25th, 2001: All exponents below 3,502,500 have been tested and double-checked.

I have some. I will get them dug out and sorted when I have a bit of time.

LOL... whoops!

I cut and paste that line from the "First Time" and just changed "First" to "Double". Yeah... I'll use the "it's late, I'm tired" excuse.

Fixed to just say "Double checks"

EDIT: Oh, and I can add a countdown to 34M being double-checked, but I wasn't sure if they'd all been assigned yet. I did a quick count and there were ~650 assignments in the 33M-34M range, but I'd have to see if there were any unassigned DC's in that range. I have the code to add that check to the page, I just need to modify and confirm.

I think after the discussions about some of these recent n-millionth milestones, there seemed to be thought that it was a little target-rich for poachers... I know I got sucked in myself. Of course there's nothing to stop someone from checking it out for themselves on the exponent reports for stuff in a certain range.

Excellent work. Gives the page a nice, clean look.

Thanks to UncWilly and some additional milestone info, I was able to fill in some add'l details. Right now I'm just missing data on the 21M and 23M single-check milestones. Thanks to the wayback machine at archive.org I was able to narrow those down to a pretty broad range within 1-3 months, but I'm leaving them out for now. I was also able to narrow down UncWilly's date ranges on a couple of them to a specific day using the wayback.

Estimated dates are denoted with an asterisk.

I also added in some info on 100M digit numbers... curious thing though, the very first LL test to check in was for M332197123 but it had a non-zero error-code. Because of that, I actually skipped to the first check-in with an error code of zero, but just keep an eye on this one...when it gets verified at some point, it would officially become the first 100M digit exponent completed. I felt bad including it now since it's "suspect":
http://www.mersenne.org/M332197123

We also have a grand total of 2 double-checked 100M digit exponents. The first one, however, was checked and double-checked by the same account, and both checked in at the same time. Different shift counts, so it should be okay but still worth mentioning. I noted it, but just to be fair I included the other one which was independently verified by different users.

It appears to me all remaining first LL tests with exponent less than 57M are now assigned.

Cool. Once we get past the < 55M and < 56M milestones I could just alter that for the 57M countdown.

If I read the comments right, it sounds like people generally like the milestones, and once the grandfathered assignments start to die off, the poaching issue should become less relevant? You won't have an assignment from 2013 chunking along super slow and "holding stuff up", in other words.
