I have put a very rough public-facing report. With no graphs or controls of any kind. But you can choose between plaintext and really-plaintext.

If someone actually uses this and wishes it has some more filtering controls, please let me know and I'll see about adding them.

Thanks, James et al.

Few appreciate the depth of peer review around these here parts... 8^>

Yes it would be nice to have the table in GIMPS ECM page extended to something like 80 digits, as for several of the lowest exponents it is just showing the curves were "done" up to 65 digits, but several people are still running larger curves that are not recorded (or at least their count not displayed). There is a rumour that significant improvements are coming to the GIMPS ECM software so many of us will certainly be wishing to record fresh curves for the lowest exponents...

If anyone knows how to get GMP-ECM to show proper curve counts for t25 and t30 please let me know.

Also if you build from source you can use `timeout 0.1 ecm -v` as the curves are now printed before any work is done.

There's also a rho_curve tool that I'm working on updating but it's largely not needed if you don't mind parsing the ecm -v output.

I don't know where George pulled the bounds from but they used 2.4e9, 7.2e9, and 21.6e9 and the counts are from the relevant columns: 350860, 567615, 930668.

Thanks for the updated data! I attached the bounds for all 322 unique curves from 2020, 2021, 2022.
