I now did the same for my two relays and I get two different
distributions, which I found surprising.  That's the relay [0] whose
results I showed earlier.

  Negotiated version | Per connection | Per host
  -------------------+----------------+-------------
                   2 |   12,236  (8%) |  9,292 (21%)
                   3 |   29,768 (20%) | 23,393 (52%)
                   4 |  108,884 (72%) | 12,051 (27%)

And here's a relay [1] on the same physical machine with almost the same
configuration.  The major difference is that this relay is not
configured to run a directory service whereas the other one is.  The
numbers are close to yours, Tom.

  Negotiated version | Per connection | Per host
  -------------------+----------------+------------
                   2 |      761  (1%) |   279 (3%)
                   3 |    4,468  (5%) | 1,301 (14%)
                   4 |   82,811 (94%) | 7,494 (83%)
