Excellent, thank you for confirming my estimates about P1 with some prior P1 done.
ECM does seem a less efficient method than redoing P1 for candidates with prior B1 of 120k150k. I'll run ECM anyway for a while and see if my estimates about factor frequency are reasonable; I imagine I'll end up P1'ing the ones that stand to benefit most after I play with ECM.

I´m back at work in low ranges.
Just started 16M, 69>70. 16.9 is currently underway. On another note, the overall < 20M subproject is now getting a huge push from the folks at SRBase / BOINC. They are sweeping through high ranges at an amazing rate, finding an impressive number of new factors. Let´s see how long this will last.

In the 4.0M range I've chosen to work in, P1 seems about twice as fast per expected factor as ECM. I have ECM running on an old laptop anyway, with P1 on a newer machine.
I found my first two factors with P1 for this effort, 76 and 81 bits. Rather satisfying! For the sake of this effort, too bad they were factors for the same exponent... When I saw a 48digit factor in the results file, I was like "awww, yea! I bet that's a record!" (for this size) Alas, just a pair of normalsized factors. Exponent is 4067587.

1,000 Days
A thousand days have passed since my first assignment in this subproject.
In those thousand days I:  Found 1,569 factors  Completed over 3,000,000 GhzDays of work (mostly thanks to my 2080Ti)  Got 50M range to less than 10 ranges with over 1,999 factors remaining  Got 40M to under 200,000 factors remaining But this is a mere fraction of the total factors found and ranges cleared by the collective. Wouldn't it be cool if when I get to 1,999 days I can declare that the under2,000 project is complete! Thanks to all.

Also, taking the figures in This post as a reference, and noting that at the time of typing my current post the number of unfactored exponents below 1G is 21 029 537, we see that in a bit more than 2 years we cleared just over 500,000 of them. Not bad, maybe another 5 years to achieve the goal that makes the subject of this thread.

Today we fell below 21M unfactored exponents: 20,999,392 as of 22:00 UTC (6 pm EDT).
Edit: It happened at 19:00 UTC: 18:00 UTC (2 pm EDT): 21,000,058 19:00 UTC (3 pm EDT): 20,999,407 Last fiddled with by ATH on 20200611 at 23:08

Yes, SRBase is knocking off the factors like a madman...he swept through all the remaining 8 million or so 7071 bit assignments in a matter of a couple months
