I like the idea of any new large addition to our pool coming on line in stages.  Even if its not statistically improbable, bringing 1/7th of the entire pool online at the same time we experience a run of bad luck looks BAD.  And I would think anyone would want to bring that much online in stages to see the results for themselves.  (I know I didn't turn on all of my antminers at once.  I brought one up, watched it for a few hours and then started another...  Staggered as it were.)
