Replying to [comment:9 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.

Yep, I also think that's normal.
> 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.
Sounds great.
If we have no time for careful analysis here, we can also just launch with
2-3-8 and depending on how that goes see if we want to bump it up to
2-4-8.
