Comment (by mikeperry):

 I have a quick observation here: If I am understanding the source right,
 the pwnage time to compromise L2 is chosen for each relay in L2. These
 times come from the adversary model.

 Since these times come from a probability distribution, the more times we
 sample it (for more L2 guards), the more likely we are to get a lower
 value for time-to-compromise for that layer. I suppose this reflects
 reality somewhat. The more L2 guards there are, the more likely you're
 able to get to one of them faster than the others.

 Anyway I agree with the ultimate conclusion of your doc. I will get
 vanguards into a state that we can run a bunch of onionperf instances with
 it and compare 2-3-8 and 2-4-8 there.
