I feel like you're going to run into lots of speed bottlenecks that aren't feasible to calculate. > Right, I was mainly thinking in terms of speedups from not having to switch tasks and the gains from specializing in one kind of computation. Switching tasks is going to be a relatively small amount of time over a 24 hr period. Given that one person can only hash 0.67 hashes per day assuming full undivided attention I'm really not sure what you could count on saving. The biggest advantage adding more people would do would make it actually feasible to calculate continuously as I doubt any human has the focus/patience for doing mundane number crunching for 24 hours without breaks. I totally get that this is all hypothetical-for-fun math, obviously nobody is going to actually try to mine bitcoin by hand. But that 0.67 hashes per day is terribly low, a 50% speed improvement would only barely put you over 1h/d. Not to mention we normally compare in h/s not h/d so it's actually 7.75e-6 H/s.
