Comment(by karsten):

 Replying to [comment:15 arma]:
 > Sounds plausible. One nice way of looking at it might be: what's the
 highest bandwidth cutoff such that the red lines in your graph lose 1% or
 less? Then the same question for 2%, 3%, 4%, 5%.

 Sure, that's something that the CDF I suggested above should show.  We
 could put percent values on the y axis and start with current diversity at
 100%.  Then you could read what x value corresponds to 99% (98%, ...).

 > Of course, that needs a definition of what it means for two lines to
 differ. We might try defining the difference as the point x where f1(x)
 and f2(x) differ the most. If there's noise, we might define it as the
 10th percentile of these points x, which would let us say "90% of the time
 there was at most a 1% difference."

 Ah, my idea was to start with a single consensus.  Combining multiple
 consensuses would be step 2.  (The data format I suggested above should
 support the graphs you suggest here.)
