bandwidths are taken from real consensus and rate limits from real server
descriptors
If you take relay bandwidths from the server descriptors and not from the
consensus, do the results change? I would guess you'll have less overall
capacity in the network, so the effect of EWMA should be even more
pronounced. Though then again, since you're rate limiting to the values in
the descriptor already, the only difference would be relays that have lots
of extra capacity but haven't changed the rate limiting from its default,
and those are probably rare.

Is it easy to do up a graph with 50ms refill rates, to see if it's more
like 10 or more like 100? That would also give us a sense of how much
variation there is in simulation outcome.
