I've been doing that since about halfway through October. As of 18/11/11, the linear regression put completion somewhere in March, so I predicted summer; I didn't get any data between 18/11 and 27/11, but since I've resumed taking data, it's gotten significantly later. (In fact I have a screenshot from three weeks ago somewhere in this forum; I'll upload a new one. Any chance I can get your data that I missed? Or perhaps we can both do it as a Google Doc? I'm currently using LibreOffice.)

Absolutely. I will upload probably tomorrow. My data was taken between the hours of 11pm and 1am CST for those days (GMT -6). Are there any certain file formats you prefer?

I would have done a linear regression already but I thought a dozen data points would have resulted in a very poor prediction. I assume you can't use Excel?

LibreOffice is capable of reading and writing Microsoft Office formats (including Excel). Would you prefer a Google Doc? (I have 157 data points, ATM.) Actually the more I think about it the better a Google Doc sounds because then (for instance) if I'm not around for a couple of days you can still collect the data. OTOH, as I think about it even more, is Google Docs capable of recording the time as LOSpreadsheet or MOExcel?

You're asking the wrong guy. To date, I have never used a Google Document.

Would you also like the all exponents below n first time and DC tests as well as all below M46 and M47 tested once?

Got a Google Doc going. PM me your gmail address; will reply with (short) directions to use (at least) my pile of data. If you'd like, you can upload your other data to other sheets.
[QUOTE=Primeinator;280744]My data was taken between the hours of 11pm and 1am CST for those days (GMT -6).[/QUOTE]
So if your data says 25/11, I should record that as midnight between 25 and 26-11?
So the first row would be midnight between 20 and 21-11?

Times are 11pm ish GMT -6 for when my data was collected. For example, the first line would be 11-20-11 at 2300 hours.

I will PM you my address in a few days. I am extremely busy with school at the moment in regards to a couple 20-page papers and my science finals.

Lol good luck with that. I have two finals on Friday and two in 8-9 days. I haven't been taking data for the other milestones, so ATM that's still up to you. I'll add the M42 data to my document though.

Just out of curiosity, are we going to make mention on the homepage that we successfully have completed the double check process for M41?

Some numbers from the milestones page:

[code]
[SIZE=2]All exponents below 24,052,939 have been tested and double-checked.[/SIZE]
[SIZE=2]Countdown to proving M(25964951) is the 42nd Mersenne Prime: 2,650
[/SIZE][SIZE=2]Countdown to proving M(30402457) is the 43rd Mersenne Prime: 58,961[/SIZE]
[SIZE=2]
[/SIZE][SIZE=2]December 1, 2011: Double-checking proves M(24036583) is the 41st Mersenne prime.
July 11, 2010: Double-checking proves M(20996011) is the 40th Mersenne prime.[/SIZE]
[/code][SIZE=2]

Congratulations on the M41 corroboration. It was worth the weight.

By my calculatons:
24036583 - 20996011 = 3040572
2011/12/1 - 2010/7/11 = 508 days

So the range was completed at a non-adjusted rate
of 5985.4 values per day (ignoring previously tested
values, non-prime even numbers, etc.)

Also: 25964951 - 24036583 = 1928368

Using the same rate yields
322.2 days from 2011/12/1, or 2012/10/19
(I couldn't calculate the exact TOD)
as one estimate for proving M42.

Since as of today there were 2650 LL tests of primes
needed to prove M42,
that calculates to 8.2 LL tests per day in this range.

I've been recording that number since, I think, sometime in October, and in fact have a month-old linear regression posted somewhere in this forum. I'll update it. (A month ago, the regression hit 0 in 3/12, so I estimated summer.)

Edit: Linear Regression: [url]http://filesmelt.com/dl/CountdownToM42.png[/url]
And the exponential regression: [url]http://filesmelt.com/dl/CountdownToM42Exp.png[/url]

The exponential regression is pretty severe. Solving for 100 tests left marks summer 2013. Solving for 500 tests left makes 29/09/2012.

The linear regression is a bit nicer. Solving for zero makes for 01/05/2012. (May 1st.)

Edit2: Oh wait, let me fill in that gap there. Primeinator has also been taking data. Okay, modified data:

Linear Regression: [url]http://filesmelt.com/dl/CountdownToM421.png[/url]
And the exponential regression: [url]http://filesmelt.com/dl/CountdownToM42Exp1.png[/url]

Not much difference regression wise. Linear regression shows 30/04/2012.

Exponential solved for 500 tests remaining is 28/09/2012. Solved for 100 tests remaining is 20/06/2013.
