 I think I've spotted a mistake in arm. It would seem that the
 RelayBandwidthBurst setting from torrc is interpreted as a rate (so a
 setting of 2MB is shown as 16Mbit/s, for example), but, as I've recently
 learned, that is not what the setting actually defines.

 What it does define is something along the lines of a "credit limit" - the
 bandwidth bucket grows with RelayBandwidthRate until it hits
 RelayBandwidthBurst. It is the maximum amount of data that can be
 transferred in a single "burst", rather than the maximum bandwidth. For a
 less incompetent explanation than my own, see
 https://trac.torproject.org/projects/tor/ticket/3630#comment:14

 This seems to be a common misconception within the tor community (even to
 the point where some comments in tor's source code indicate it!).
