Second half of 54.4M
Now "reserving" for 30 days all the exponents in
the second half of 54.4 M that has B1=B2≤730,000 [B]and[/B] without a DC. Currently working on:  54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000)  the whole 54.4 M (B1=B2≤730,000) 
[QUOTE=Ensigm;562166]Cat 1 exponents with only Stage 1 P1 are surprisingly rare. I'm now "reserving" for 30 days all the exponents in
 54.36 M, 54.37 M, 54.38 M and 54.39 M that has B1=B2≤730,000 [B]and[/B] without a DC. These "reservations" only apply to factoring.[/QUOTE] In many of the 5xM, 4xM and 3xM ranges they will be rare because of the work I (and others) have been doing there the last 3 years working on the sub2000 project here: [url]https://www.mersenneforum.org/showthread.php?t=22476[/url] In short the goal is to get all 0.1 Million ranges to below 2000 unfactored exponents. For example here 39.3M and 39.6M are the ranges not below 2000. [url]https://www.mersenne.ca/status/tf/0/0/4/3900[/url] We achieve this by more bits of TF and deeper P1 especially where B1=B2 or they are relative low. 
First half of 54.5 M
Now "reserving" for 30 days all the exponents in
the first half of 54.5 M that has B1=B2≤730,000 [B]and[/B] without a DC. Currently working on:  54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000)  the whole 54.4 M (B1=B2≤730,000)  the first half of 54.5 M (B1=B2≤730,000) 
Previous ranges 54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000) should now be finished and I am "unreserving" them.
Report for the whole 54.3 M: 5 factors found in 81 attempts (6.17%). Based on the bounds that were used, expected probability would be between 3.78% and 3.81%. Currently working on:  the whole 54.4 M (B1=B2≤730,000)  the first half of 54.5 M (B1=B2≤730,000) 
Second half of 54.5 M
Now "reserving" for 30 days all the exponents in
the second half of 54.5 M that has B1=B2≤730,000 [B]and[/B] without a DC. Note: this will be the last range I take in Cat 1 for a while. I will be going on a vacation shortly, and my maximum throughput will decrease by about 2/3 and will also become less constant. As a result, I will be moving away from smaller exponents so that those with higher throughput may take them.

[/QUOTE] When you are done there could I interest you in bringing that kind of P1 power to these ranges to help with my sub2000 project: 48.4, 49.6 It's just over 1,500 exponents with similarly low B1=B2 And if that's not enough I can find more. Thx 
[QUOTE=petrw1;563195]When you are done there could I interest you in bringing that kind of P1 power to these ranges to help with my sub2000 project:
48.4, 49.6 It's just over 1,500 exponents with similarly low B1=B2 [/QUOTE] I will probably first go over all exponents under M48 with B1=B2<700,000 and no DC. That's gonna be at least until this year's end. Then I will either go into sub2000 project or "regular" firsttime P1, or do both. Also don't think that is lots of P1 power. I'm currently just over 120 GHzd/d and will soon go down to around 40 GHzd/d. If you have over 1,500 exponents spread in 2*0.1M ranges I will probably take only 0.01M at a time. 
Second half of 55 M (B1=B2≤690,000)
Now "reserving" for 30 days all the exponents in
the second half of 55 M that has B1=B2≤690,000 [B]and[/B] without a DC. Currently working on:  the whole 54.4 M (B1=B2≤730,000)  the whole 54.5 M (B1=B2≤730,000)  the second half 55 M (B1=B2≤690,000) 
First half of 56 M (B1=B2≤690,000)
Now "reserving" for 30 days all the exponents in
the first half of 56 M that has B1=B2≤690,000 [B]and[/B] without a DC. Will also try to reserve them as TF assignments.
