I haven't figured out how to calculate the probability, but here is a quick simulation to get an estimate:

That is actually good news.

But, to be clear, I'm not suggesting that we start doing fractional bit TFs from PrimeNet's perspective. The idea is still to do full bit levels, but break them up...

This is a misconception. The correct way to read that chart is: "It is "optimal" to TF to 78 bits before running two LL (FC & DC) on the same card"

Yes, running multiple workers on that CPU will trash the cache. You're probably better off running a configuration of two workers, each using 4 threads (i.e. one worker per CPU).

No need for different n. As you said, it is just simple scaling. But bit levels, yes. And for Nvidia and AMD differently.

How does it impact the runtime for the WU?

Side question: Is it worth it, for those who have sufficient RAM, to override the -A parameter back to 32?

I am kind of confused. The quote from wikipedia says that P/VP/C are still required to do online disclosure. So who _does_ it actually exempt? And how did members of Congress benefit from it?
