 >  5. Number of introduction points established on the same relay (in the
 measurement period): This graph shows to what extent relays are being used
 for establishing introduction points.  The agorahoo service serves as best
 example here: while about half of the about 1300 relays have only been
 used a single time for establishing an introduction points, the other half
 was used more than once, up to almost 60 established introduction points
 on a single relay.  This distribution looks plausible, given that tor's
 weighting algorithm favors relays based on their consensus weight.  It's
 more difficult to analyze the other services which have only established a
 tiny number of introduction points in the measurement period compared to
 agorahoo.  On a related note, if services were to change their preferences
 for selecting introduction points, that would stand out very clearly in
 this graph.

 Karsten this is great and this set of graph is quite useful for deriving
 conclusions.
 May I also ask you to make a second version of 5. but without the agorahoo
 hidden service? It's dominating the graph and it's hard to read the
 behavior of the other hidden services (even though it looks pretty
 normal).

 I think after that, we are done with the graphs here and we can write an
 analysis paragraph or something.
