Tor clients build paths with 3+n hops, where n is the number that are
influenced by some third party. So for example, when you're doing a
hidden service rendezvous, you typically end up using 4-hop paths --
3 that you picked, and 1 that the other side picked.
In fact, for client-side introduction point circuits, in some cases you
could end up with 5-hop or 6-hop paths, since if an intro point fails,
the client just extends the existing circuit one more hop to the next
intro point to try it.
Hope this helps,
