 The reverse is to expected and it's often up to 1000 relays.
 However, the mismatch in this case is often anywhere from 1 to 100 relays.


 How to replicate:

 {{{
 #!div style="font-size: 80%"
 Code highlighting:
   {{{#!python
 serverdescriptors_dict = dict((str(x.fingerprint), x) for x in
 DescriptorDownloader().get_server_descriptors().run())
 consensus_list = [x for x in DescriptorDownloader().get_consensus().run()]

 mismatch_count = len([x.fingerprint for x in consensus_list if
 x.fingerprint not in serverdescriptors_dict])
   }}}
 }}}


 Here are the results from multiple runs:

 88
 16
 91
 1
 1
 86
 1
 88
 90
 90
 17

 Unclear where this bug is, it could be in the TOR protocol itself perhaps.
