No worries. :-)

That goal does not apply to the R2 2nd conjecture, which was only started a few months ago by me well after the goals were posted. It only applies to the R2/S2 even-odd k-n conjectures. For S2 BOINC already completed those to n=8M. For R2 all of those are currently being searched by BOINC and are currently at n=7M.

There are 7 k's remaining for the R2 even-odd k-n conjectures that are at n<8M. They are:

2 even k's on regular R2 1st conjecture; k=351134 & 478214
1 k on R2 even-n; k=14361
4 k's on R2 odd-n; k=39687, 103947, 154317, & 163503

They all began the year at n=6.65M hence the 0.35M / 1.35M completed as shown in the first post.

By my estimate there is a pretty good chance that BOINC will complete the goal. If I think they will fall a little short I will contribute some of my machines to BOINC in Nov. and/or Dec.

We may have a 2022 goal to test the R2 2nd conjecture to n=4M or 5M. We can see what we think of that later this year. Pepi had offered to have Yoyo sieve it when I was done with it to n=2M. I'll send him a nominally sieved file for n=2M-5M in the near future so that he can have Yoyo sieve it.
