IMO we should choose a reasonable balance and fix it in the document. We
should care about packet size for sure, but 64 hashes are not that much
work.

Hi Yoav,
First, I raised a third concern, which is that allowing the client to decide on
the difficulty of the puzzle it is willing to solve adds unneeded complexity.
Basically the client doesn't have enough information to make a good decision.
To answer your question, I think we've already been down this path and reducing
the variance is certainly a good thing.
I’m sure that less variance is better than more variance, but that comes at the
expense of more work for the responder. So do we set the number of returned
results to 1, with minimal work for the responder and maximum variance? Do we
set it to 8, with a nice balance between fairness and responder work? Do we
set it to 64, with a huge packet, a lot of responder work and maximum fairness?
Or do we let the responder decide and communicate through the challenge, which
has some complexity cost?
