Expect more users during the formula boinc (challenge dates yet to be known) plus and hopefully it can get chosen as one of BOINC decathlon discipline.

I´m back at work in the 16M range, TFing from 69 to 70 bits.
It´s a pity we can´t reserve TF work for these ranges using the Manual GPU Reservation form, in order to reduce the chance of toe stepping, but it seems actually impossible: the server gives a message indicating no assignmens are available... More precisely I´m currently working the 16.58 and 16.59 ranges (~ 300 exponents). Will keep you posted on the progress.

I have an offline PC doing P1 on 35.3M. Could be a few weeks before I upload the results.

Have now taken the whole 16.5x M range (just over 1000 exponents to go). Factors are slowly popping up: 12, so far.

I have completed aggressive P1 for 4xM ranges ... TF anyone?
There are only 3 ranges remaining in the 4xMillions but they are stubborn.
42.6: 47 remaining 48.4: 49 49.6: 49 I have done aggressive P1 on these 3 ranges. Every exponent is P1'd to at least a 3.5% factor rate; many to a 5.25% factor rate. I estimate that to continue P1 would require about 500GhzDays per P1 factor. Therefore, I am suggesting that the preferred next step is TF with a nice GPU farm. They are currently factored to 74 bits. To complete these ranges will require full TF to 76 bits; then about half the exponents 77 bits. A total of about 2.5M GhzDays of TF. Thanks for everyone's help.

I am nearly done with the 27.1 range (got still a dozen of expo left). As per petrw1 suggestion i'll take the 23.5 range next.
As for stats, I have done around 586 tests and found 39 factors. Wich is about a 6.65% rate.

New tool
Don't get too excited, but....
Prime95 30.6 has P+1 factoring available. Maybe this will help a tiny bit with some of the more stubborn ranges. See https://www.mersenneforum.org/showpo...&postcount=150

I read the posts last week discussing it and asking for it. Thanks

Indeed. Thanks George!
I don't have many human cycles at the moment, but I do have a few CPU cycles to burn... Could anyone give me an example of a P+1 worktodo line that would be appropriate for the <2K subsubsub project? Also, how can we tell what's been "worked", so we don't duplicate other's efforts?

More on P+1
George: Your posts talks about choosing B1 based on the current ECM B1.
For my case do you have any recommendations for P+1 for choosing B1 based on how much P1 has already been done? I am tempted to assume that P+1 will find different factors than P1 which makes me hopeful even smallish B1/B2 will have reasonable success? Am I totally out to lunch? Thanks

Since this is brand new work type, nothing has been worked as of yet. But all reported results should show up under the exponent's history (in theory). I don't know if this information will be readily available anywhere else.
