It need time to get all the info. It is now listed as a TF find

It does, you're just not seeing it.

I'll guess that you looked at the exponent page immediately (at least same day) after having found the factor. Newly-discovered factors are added to the database every hour (from the Recently Cleared list), but details about who-did-what-when only get imported overnight (~1-2am UTC). The exponent pages at mersenne.ca are heavily cached, so if you're not seeing it in your browser, try Ctrl-F5 to forcibly-refresh the page and the result should show up for you.

Thanks for the explanation. That might very well have happened in the way you described. Now it is also displayed for me.

mersenne.ca server migration and probable downtime (Nov 2020)

[James Heinrich]

There is some unexpected data in the nightly PrimeNet export, waiting for Aaron to fix, stats and such will be delayed.

edit: Fixed now.

[James Heinrich]

Putting the site in the short-term suspended state while I apply a database change. Should only be a few minutes (... I think)
edit: and we should be back.

For those who use the Worst P-1 tool, the calculations have changed. Previously the P-1 probability was calculated as being done after the TF which has been done on the exponent. The problem with this is that if an exponent has had abnormally-high TF then the apparent probability for the P-1 drops very low, even though it was done to reasonable bounds. The new calculation is done as assuming TF was done to GIMPS-standard, which makes it easier to find P-1 that was actually badly-done and should no longer falsely report an exponent is a candidate for a better P-1 when the first P-1 run was fine but also had very-high TF.

This will mostly affect the lowest exponents that have had considerable factoring effort of all types, but it will also impact the "expected" values for what makes a good P-1 or not. As a rough approximation, where you say 2% before would be a rough analog to 5% in the new system.
