New description:

 Tor Weather currently uses descriptor bandwidth to inform operators if
 their nodes are not providing sufficient capacity for various things. This
 may be useful for some tests, to simply tell relays if their relay stops
 transmitting any data, but it probably shouldn't be the only thing we
 check.

 Using the "Bandwidth=" values from the !NetworkStatus documents will allow
 us to also determine if a relay appears drastically underloaded, or
 overloaded as compared to it's peers. The best way to do this test is
 probably to take the "Bandwidth=" value and divide it by the descriptor
 bandwidth value. If this resulting number is 1.0 or larger, the relay is
 doing as well as or better than other relays. If this value is very low (0
 is obviously lowest), then the relay is having trouble transitting data,
 and is that much slower on average than others.

 So this is probably best classified as an enhancement, not a defect.
