less effort. I won't comment about your claim of "logic and common sense". I'm sure that Dunning and Kruger would have something to say about common sense in a technical subject when one lacks the proper background. The tables that convey the work that has been done are public. But without introductory text that explains the "conversion", someone might actually think that for (say) M1277, 360,000 curves with B1 = 800M were actually run. And they weren't. Also, someone who tries to use them to decide on a parameterization for the next higher level (say) 70 digits, will not be able to so with a lot of accuracy because the "conversion" has destroyed the needed information. Running a t65 does include the possibility of finding a p70. One can't know what that probability is with the conversion that is taking place. If you bother to read my paper, selecting parameters for the next level requires computing a Bayesian posterior distribution using a prior [given by say Dickman's function] and the pdf of the actual trials. These tables destroy that last piece of information. The people arguing with me don't seem to care. That is their prerogative. Code has bugs. They get corrected. With respect to published tables, this table may be considered to have "table bugs". Should these not be corrected? There is no way to discern, from the published tables, that data has been "converted". At a minimum, the people maintaining them needs to correct this by adding appropriate text. I did not know about the conversion until this current thread was posted. (!!!) Not having the time to fix the tables [or no longer having the needed data] is understandable. But not adding explanatory text is simply bad. Last fiddled with by R.D. Silverman on 20191122 at 13:28 Reason: fix pagination

There is a way to find the curve count done for each B1, for example
https://www.mersenne.org/report_expo...ll=1&ecmhist=1 gives the detail information for M1277. It contain many lines, the latest is DateUserTypeResult20191119Ryan PropperNFECM5676 curves, B1=7600000000, B2=42000000000000020191119Ryan PropperNFECM34000 curves, B1=2900000000, B2=10510123721791220191119Ryan PropperNFECM7012 curves, B1=1000000000, B2=1907117672461620191119Ryan PropperNFECM95084 curves, B1=850000000, B2=1489938239791820191119Ryan PropperNFECM14856 curves, B1=260000000, B2=31785598845162019111654875487NFECM100 curves, B1=100000, B2=100000020191029pfrakesNFECM37 curves, B1=1500000000, B2=1500000000 Give a summary of each different B1 and B2 maybe useful, but that would increase some coding work.

Superb. But I can't open the webpage. I've tried several times and Chrome just spins then times out. Is the server overloaded with requests?

https://www.mersenne.org/report_expo...o=1277&exp_hi= Then click on the 1277 in the far left hand column. Here's a shortcut to where that takes you: https://www.mersenne.ca/exponent/1277 There you can see the detailed curve information you are looking for if you scroll down far enough. If you want to see it broken down even further (by user), click on the ECM Details button.

But note that the latest and grandest results from Ryan, the ones that really made a difference in the curve count, are not (yet?) listed...
