GIMPS Milestones

There are these nearest milestones as of October 24, 2011:

Quote:

All exponents below 22,545,883 have been tested and double-checked.
All exponents below 38,103,407 have been tested at least once.
Countdown to testing all exponents below M(42643801) once: 166
Countdown to testing all exponents below M(43112609) once: 227
Countdown to proving M(24036583) is the 41st Mersenne Prime: 2
Countdown to proving M(25964951) is the 42nd Mersenne Prime: 3,951

I guess something great will happen soon - proving M(24036583) is the 41st Mersenne Prime: 2. But what does "2" mean? Days or what?
Is it tightly related to the 1st milestone - double-checking all exponents below 24,036,583 should be completed first?
Would you be so kind to describe these milestones a little bit? Thank you!

2 exponents left to check.

Yes, intimately related. You can't have one without the other.

More specifically, here's a list of all unverified LL tests between 1 and 24036583.

You can see that the smallest unverified residue is 22,545,883, as well as 23,480,917 at second smallest.

Based on other information I'd estimate mid-November before these are complete.

Thanks guys! I should have thought of exponents not days when after two days I saw that counter have't changed :) It's interesting how long it takes double-checking of the next exponent

I've been keeping a record since 4100 or so, and the current linear regression pegs completion around the end of May (03/26/2012 20:10:58 to be exact). Of course right near the end, the rate will slow down a bit, so I imagine sometime over the summer.

Is it March, or is it 05.26? I did not get it...

In other news today, Dubslow discovered he does not know the names of the months.
Edit: Or he can't tell the M's apart. One or the other.

Yes, I meant March, though I still stand by the summer prediction.
