Sadly not everyone follows this forum.
I also had a squatter on the 1.1M I reserved.

That said Harlee did officially request 8.0 and 8.6 here so maybe he'll respond.

I look at the last 30 days activity in a range before I start it and then if someone jumps in hard where I am I may move on.

So... I'm kinda done with 1.0m. There are a few ones with high B1/low B2 combinations that I don't want to touch. Apart from that, everything is done to decent depth.

Now all these ranges have 4000 exponents with known prime factors. So I unreserve them.

Interesting goal; moving on to 17.x next?

I want to reserve 17.6M, 17.7M and 17.8M.

The range 17.1M requires extra TF that I cannot perform because I do not have a powerful GPU.

I'm not sure. It's already 50-50 at 74/75 bits.
Might get 10 factors to finish it to 75 bits.

This range might just need more aggressive P1.

Your call.

petrw1 · 2022-06-30, 15:56

Wow yesterday I found 10 P1 factors in 20 attempts including 2 in a row twice and 3 in a row.

And while you were having this great success, over 3 days, I had 73 no factor found P-1 results in a row.

Now I feel bad.

For the record my record for this project is 115 without a factor.

Of the remaining un-factored exponents under 20M that are worthy of more P-1 (IMHO):
Changed Bounds: 8334 (In most cases considered complete unless the Bounds changes were too small)
Percent of Worthy: 3.15%
Factors found: 494
Percent of Changed: 5.93%
Still Worthy: 257,210 --- Granted my criteria is somewhat aggressive; will choose more than you might choose

Including TF and ECM for all exponents up to 50M:
New factors: 585

New Ranges "Cleared" (Or really close depending on your criteria)
0.2
1.0
1.2
9.9
12.1
Many more ranges only have a few hundred exponents worthy.

TF Tidy-Up below 50M (getting all exponents above "x" bits):
All exponents above 38.1M at 73+bits
All exponents above 36.8M at 72+bits

Recently, I mentioned that user harlee had reserved many exponents in my range, 8.8M. A few days later these were all released. Now a another user, Cong Shengzhuo, has reserved many of the exponents in the 8.8M range. This is becoming annoying.
