Comment(by karsten):

 There are three new graphs attached to this ticket:

  - The [https://trac.torproject.org/projects/tor/attachment/ticket/2394
 /bandwidth-comparison-relays-2011-04-20.png first graph] shows empirical
 cumulative distribution functions of ratios of measured by self-reported
 bandwidth for six categories of relays in the consensus from January 24,
 2011 at 00:00:00 UTC.

  - The [https://trac.torproject.org/projects/tor/attachment/ticket/2394
 /bandwidth-comparison-relays-votes-2011-04-20.png second graph] compares
 ratios in votes to the ratios in the consensus for the six categories.
 The black line is the consensus, the gray lines are the four votes.

  - The [https://trac.torproject.org/projects/tor/attachment/ticket/2394
 /bandwidth-comparison-measured-votes-2011-04-20.png third graph] uses
 measured bandwidth weights on the y axis rather than absolute relay
 numbers.  This graph is somewhat misleading, because it over-represents,
 well, relays with high measured bandwidth (surprise!).  I wonder if
 there's a better weight to use here.  The second graph is probably more
 useful than this one.
