Default 1000<k<2000

I am considering working on quite a few k-values in the range 1000-2000, possibly even creating a new RPS stats page if others are interested in working in this range also.
If you have done any work in this range, please post k and range searched in this thread. If you would reserve a value or appreciate stats on this range, let me know (PM or reply in thread).
Amphoria, I have your k-values from your website: 1013, 1031, 1039, 1121, 1153, 1169,1173,1223. I also found Gryphon has 1001 on the Primesearch website.

Primesearch has a nice site for 300<k<1002, thus my interest in the next uncharted range. k<300 is well-searched under 500k, but there's more "joy" for some in searching lower n-ranges.

It seems that Peter Benson (L80) is testing the whole 1000<k<1400 area.
A few years ago I tested the following (birthday-)Ks: 1009, 1103 and 1505 (each up to about n=500k). There are probably others working in this range too. So, perhaps, you should check the primes pages for more information.

I am testing k=1515, currently near n=600000.

A new RPS stats page sounds worthwhile.

I have done some work in this area but the spreadsheet with my data on is currently on a broken PC. From memory (please consider these reserved):
1449
1785

I also have lists of primes from about k=1000 to k>2000, in steps of 21, n up to 15000.

I will transfer the HD from the broken PC asap.

I have to say that I had got the impression that Peter was only checking for proth primes, but I see from checking his prime page he appears to be searching riesel primes as well and appears to have got to about n=380k. I picked my ones on the basis that no-one had ever found any primes and registered them on the primes pages. However, they mostly have weights between 1000 and 1500 and so it may be there aren't any primes in the range that Peter has searched.

Curtis, if you put the page together could you extend it up to k<3000 as I am also sieving some >2000 and I get the impression that Thomas is also searching some k's in that range.

That's true.
I tested all k not divisable by 3 in the range 2000<k<2300 for n=200k-300k.
And I'm currently sieving and testing 52 k out of the range 2000<k<2400 with the condition k%30 = {7, 11, 13, 29} for n=300k-500k. LLR testing is around n=350k now.

If you like, I'm willing to release them for another team drive. But they'll need a little more sieving, and you should note that these are the "not so prolific ones" (e.g. low density)...

Given that there is a high likelihood that Peter Benson has already searched 1013, 1039, 1067, 1121, 1153, 1169, 1173 and 1223 in my current target n range I intend to stop searching these. However, please leave 1031 marked as reserved by me - this is lower weight and I have already taken it to to n=800k.

I have also stopped searching k=2047 from my website as Thomas is searching this.

There is clearly enough active work in this range to deserve a stats page. I'll start working on such a page. Let's use this thread to reserve k-values from 1400 to 2000 for now, expanding in the future. I'll add the 2000-5000 reservations at the bottom of the page so there is public record of the work that has been done.
Before you begin work on a new k-value, I strongly suggest you search the Prime Pages for it and make sure there is no record of previous work.

I'm going to study Larry's excel file on weight vs primes and pick a few k in 1400-2000 to test under n=600k. I want to find some more small primes!
