That said, I could get a very close estimate by checking the count differential over a defined time period. Accepting the fact that the count could not differentiate between TF, P1, ECM, P+1 factors. I've done this for a few other COMPLETE ranges. Last fiddled with by petrw1 on 20220806 at 14:52

Thanks for editing the list on post #1. For the 8.1M range, I have tracked TF, P1 and P+1, and found that the 102 exponents newly factored are all done by Flaukrotist via P1. So the number 102 for 8.1M is totally correct now. For the 1.0M and 9.9M range, I think I am able to check it manually in a few days, distinguishing all TF, P1, ECM and P+1 factors, and selecting those which were newly factored by P1. And I will see if these numbers match. Last fiddled with by congsz on 20220807 at 00:14

I am less than a week away from finishing the 4.2M range with only 57 exponents left to test. So far I have found 156 factors in this range and hope that I can get another 4 more by the end of the range. I'll let you know the final count this week.
I am planning on continuing on up into the 4.3M range so could you please reserve it for me. I finished 3.8M a while back so you can change it to. 3.8 DrobinsonPE  COMPLETE (64)

1.0M Checked, The Number 73 Is Correct
Quote:
The factoring status in 1.0M is more complicated than that in 9.9M, as factors are found by multiple users. The process can be explained as follows: Code:
1. Numberwang started P1'ing in this range from January to March, with M1011277, M1020751, M1037303, M1046527, M1059209 factored. But his bounds are too low for the project, roughly B1=100K, B2=2G. 2. axn started P1'ing from March till June, completing this range with 64 newly factored exponents. 3. Jocelyn factored M1056481 this February. LordJulius factored M1006237, M1029481, M1009417 this year. To be honest, I don't have any secret for finding this data. What I have done is actually LOTS of manual work. I do my search in the following three steps: Code:
1. Go to mersenne.ca PrimeNet visualization tool and compare data between the most recent and last November. I can get a number (e.g. +73 Factored). Indeed, this number cannot distinguish P1 from TF or ECM... 2. Go to mersenne.org Reports>Detailed Reports>Factors Found, search for new factors found in the range, between last November and current day. This can get a detailed "ExponentFactorDate" chart. However, this cannot distinguish P1 from others, either. 3. Copy the chart you get into a .xls file. Manually open the "Exponent Status" page for EVERY EXPONENT in the chart, and check ONE BY ONE whether it is a newlyfactored exponent or not, whether it is factored by P1 or not.

I'm almost done with 8.8M; so, sign me up for 8.7M (the one I was working on when the other project finished).

4.2M is done. Started with 1992 unfactored exponents. By my count, I found 164 factors and it looks like someone else found 1 because the current count stands at 1827.
4.2 DrobinsonPE  COMPLETE (164) Update on the other ranges: 4.0M is almost 50% done with 50 factors found. 4.3M just starting.

My count shows that Code:
4.20M 12 4.21M 15 4.22M 17 4.23M 7 (1 composite factor, counted only once) 4.24M 19 (1 composite factor, counted only once) 4.25M 19 4.26M 18 4.27M 15 4.28M 19 4.29M 24 (2 composite factors, counted only once per composite factor) Last fiddled with by congsz on 20220811 at 04:15

I went back and checked. My records matched up until today. Turns out that I missed 4299397 this morning. I was busy tonight so when the count was off, I just assumed that someone got lucky with an ECM.
My count for each sub range now matches the results you found so the list in post #1 should be: 4.2 DrobinsonPE  COMPLETE (165)

8.8M Complete
I think I have completed 8.8M. 155 factors found by P1 (1955 attempts). Also, 6 factors found via trial factoring with mfaktc (955 attempts).
