For all we know, they are only tested to n=5000; which doesn't allow adding them to the 1k thread or the proven/1k/2k/3k listing thread. 2. Without a primes file, all that we can show on the pages is "testing just started". If you haven't yet reached n=25K, it's better just to reserve them and mention their 1k status when you reach that limit along with posting a primes file at that point. I agree about checking all bases on the other side that have been proven on one side; that is if the CK is fairly similar. I've done a little of that myself but not extensively. 
Ian,
You can go ahead and send me starter HTML pages for both sides of 580, 932, and 1010 even though 5 out of 6 of them are CK>200. Gary

Haven't reached 25K with either of S/R580 (but close; see attached).
In fact, I have never imagined that S580 k=406 will go as far as it presently did. It is amazingly heavy and yet... still goin' and goin'. 
I'll heed my own advice and will develop R610 (because of the proven S610),
as well as R850 and S850 to n=25K.

It's interesting that you call it luck, implying bases that have been the most "lucky" score the highest. I think that in most cases, it's not luck. It's that the bases are heavier weight, i.e. many of their k's have fewer small factors, than normal. Clearly there is an element of luck but the absence of small factors on most/all k's is the biggest contributor to proven bases scoring high. Note that none of the bases are b==(2 mod 3). Bases that are (2 mod 3) have been notoriously difficult to prove. That brings up another question: What proven base that is b==(2 mod 3) scores the highest using your formula?

For example, if we were able to prove Riesel base 6, it would score 6*sqrt(84687)=1746. That's pretty low for what would be a relatively difficult proof. The even more difficult Sierp base 6 would only score 6*sqrt(174308)=2505. It has 19 k's remaining at n=327K and is unlikely to be proven in most of our lifetimes without new mathematical methods being discovered. I wonder if taking the log of the base would work better. OK, let's try log(b)*sqrt(CK) and see what we get: S36 = 67.58 S57 = 60.52 S337 = 58.41 S589 = 56.36 S580 = 56.23 S903 = 54.34 S57 would be in 2nd place. This all seems reasonable. Now...if these were to be proven: R6 = 226.45 S6 = 324.88 That seems to more accurately reflect the difficulty in proving base 6 on both sides. Would you agree? If so, can you plot that function? That would be interesting to see. Gary

This looks something like below (log is log[sub]10[/sub] but this is just a question of scale).
This concept is somewhere between difficulty and luck. This measure is a tongueincheek, anyway. Luck is involved to a certain degree. For example, one may have tested a conjecture to 100K, but the prime is waiting at 100.5K and the conjecture remains a 1ker...

You don't have to wait on this one to download which is why others use that upload site.[/quote] The general consensus is that sendspace is "clean" in that it's not going to try to stick some kind of malware on your system; but it still does give you tons of annoying popups. I suppose that's what they have to do to pay for it, though: it's the only free fileuploading service out there that can do up to 300 MB. (Besides megaupload, that isthey can do 500 MB, but their ads are even more obnoxious.) I usually use sendspace as a last resortif something doesn't fit in email, for instance. 
[quote=henryzz;226491]Shouldn't these be Ian's to process as they are all CKs<200?[/quote]
I've downloaded from Sendspace a few times. It's "clean" as far as I know. But like Max said, full of ads/popups and stuff. What I disliked this time around is that it had a link that said "download" on it and instead of downloading your files, it started to download someone's ad site before I stopped it. I then found the correct download link at the very bottom. Popups/ads are OK as long as the site is providing a good service to the public, which it is, and not sending malware or trying to load some task bar on my windows, which it appears not to. Misleading links that cause people to accidentally click on them get me irked in a hurry just like misleading sales in retail stores do. Ian is actually doing CK<=500 now. You can send stuff to either of us. We'll work it out between us. But yeah, if you happen to see that it's CK<=500, it'll save us a little time if you send it to him.
