With the power of yoyo@home, is it even worth anything for me to run 11e7 curves? I'm only a little over 250 right now and one of my machines even refuses to do stage 2:

Not really. Even if you would like to find a record factor, the conditional probability of success of any curve is dropping down to zero as I am typing... (Conditional on that yoyo@home already ran 10^4 curves at this moment and didn't find a factor.)

Will be 18000 curves @ 11e7 enough or is there more needed?

You could always ECM at a t80 level and go for a record ECM factorization

The trouble for me is that as I increase B1, more and more machines fall by the wayside. At 43e7 more than half tell me to get lost. And, I just can't see my attention span lasting for that long anyway...

If my estimation is correct (i.e. if I have no mistakes in my tables), ~2*t55 = 2*18k = 36k curves @11e7 are are needed for a c173.

Edit: I just see that you have queued 42k@26e7. This might be a bit of trying for record factorization, but why not...

No factor found so far with 40k curves @26e7.
