Comment (by catalyst):

 If I look at https://lists.torproject.org/pipermail/tor-
 dev/2015-October/009763.html I still sense some terminology ambiguity when
 referring to hops.  Counting OR nodes is probably best rather than
 counting edges.  In a normal circuit where a client connects to a public
 address, there are 3 OR nodes, right?  In a normal hidden service circuit
 there are 2 OR nodes between the client and the rendezvous point (3 ORs
 total counting the RP) and 2 OR nodes between the hidden service and the
 RP (3 counting the RP itself) right?  Or am I misinterpreting something?
