Why?

The current tests that we had in there for base 2/4 were at n=6.65M or ~2M digits. It got little to no interest for the last several years.

3677878*3^n-1 is at n=5M, which is ~2.385M...

The server has dried out after the effort was completed to n=6.65M.

Riesel/Sierp base 2/4 even-odd k-n will now be turned over to BOINC. It will be started after additional sieving is completed...

Why 15 seconds? Tests for R3 at n=75K-80K run about 6-8 secs on a modern I7-9700 with all cores running. Plus there are many tests that will be removed by k's found prime. You could have probably...

Are you sieving only k=35G-36G ?

I posted those sieve files for R3 as fully sieved to P=35G using srsieve. What is your test time at n=80K for R3? I suggest that you use n=80K for a test time. ...

I have Sweety blocked and just delete all of his posts now without even knowing what they say. It makes my job a lot easier.

I will leave this one since it was responded to.

Optimum sieve depth on those averages P=~15G and they are currently only at P=1G. That is a serious effort for most folks, even for just sieving. Yoyo cannot do them because it's too many k's.
