[QUOTE=rogue;274910]What??? Isn't S63 keeping you occupied? :smile:[/QUOTE]
Occupied, yes. Entertained, weeeeellllllllllllll..... but there's light at the end of the tunnel :smile: 
I'd like to make an "unofficial" recommendation: Both sides of base 150 to n=25K. Completing these would put all bases < 190 with CK < 100K at n=25K. These bases shouldn't be too bad for some of our regular heavy hitters. Both have a CK=49074 and I expect them to have 200250 k's remaining at n=25K. I have already tested them to n=2500. At that depth, R150 has 427 k's remaining and S150 has 401 k's remaining.
If anyone is interested in them, I can post the list of k's remaining at n=2500. After R150/S150, the only base < 200 with CK < 100K that would need to be tested to n=25K is R193. But it is kind of a bad one. With CK=80802, it has 844 k's remaining at n=2500. In a couple of weeks, I'll "officially" add to the recommended list bases < 256 with CK < 100K that have not yet been done to n=25K. There are something like 68 of them and I have done them all to n=2500. As for difficulty, most of them are somewhere in between R150/S150 and R193. Gary 
10 new bases have been added to the recommended list. There is an attachment with each of their k's remaining at n=2500. R150 & S150 would be the highest priority. Completion of them would complete all bases <= 190 with conjectures k<100K to n=25K.
Edit: Completion of all 10 bases would complete all bases <= 256 with conjectures k<100K to n=25K. 
Mathew has been kind enough to provide us with some more sieve files for the various bases recommended to n=25K. They are on the reservations pages and are shown with an asterisk in the first post of this thread.

Mathew has provided sieve files for both sides of base 223. All recommended new bases now have links to sieve files on the reservations pages.

I have a recommendation of all 1k bases <= 256 up to n=200K.

I received an interesting analysis from Ian. In it, he suggested testing all bases with 3 or 4 trivial factors that have a CK < 1M. These bases should have fewer k's remaining then most bases of similar size and CK. The analysis is attached. I have added the bases to the 1st post of this thread with a link to this post.

Several of the new recommended bases in the 1st post here have been tested to n=2500 and sieve files have been provided for n=2.5K25K.

I have added R106 as recommended to n=25K. It has already been tested to n=10K with k<=100K already tested further to n=25K. There is a fully sieved file on the reservations page with the 1578 k's remaining for the range of k>100K and n=10K25K.

I have added R451 and S451 for n=10K25K to the recommended list. Ian recently completed them to n=10K. There aren't too many k's remaining.

I have added S79 for n=2.5K25K. For completeness, I also added R51 for n=10K25K, which is currently being worked on by Lennart.
Completion of these would put all bases <= 100 with CK < 20M at n=25K! :smile:
