You and I are both correct.

If someone wanted to figure a fair exchange rate on this, I might be willing to do it in exchange for a GPU doing TF on exponents in the 332M range to bring them to the recommended bit level. I could take one of my borged boxen ( Intel Core i7-9700 @ 3.00GHz) and dedicate it to the task for a while.
[When I looked up the details on this machine on PrimeNet to post it I found out it (and another borg) had 8 cores vs the 6 I thought. I changed the settings and am now employing all 8 of those.]

30 TF from 78 to 81 bits at 100Mdigit? Or 30 P-1 to adequate bounds?

I have started the exponent and gotten it assigned. Prime95 says 3 months to go. I don't know if that is the right exchange rate, but I will do it. I think that if they are currently at 78 bits that is closer to fair than just bumping some from 80 to 81.

I estimated 1 in 30 would get factored and eliminate need for a PRP. 40:1 P-1 might be equal effort.

I've reserved these 31 in P-1 and will also TF the survivors as below.

Code:
Factor=332309569,78,81
Factor=332327231,78,81
Factor=332327243,78,81

Cool. I expect on Tuesday the estimate of when the LL gets done will be better. This is a relatively new borg so the rolling average is not perfect. I moved the Cat 1 DC's it was doing to another machine.
