Comment(by Sebastian):

 Replying to [comment:9 arma]:
 > In further poking, the fractions that relays are advertising are
 assuming that all clients use the weights in the consensus, which only
 started happening in mid 0.2.2. So all the 0.2.1 clients are fetching
 directory stuff according to different weights -- before the
 WEIGHT_FOR_DIR rule existed.

 Another idea for why we see spikes would be that when the weight changes
 that isn't immediately reflected in load, because (0.2.2.x) users still
 have the old weight until they get a new consensus. So if there is a sharp
 drop in weight, the user number might be heavily inflated.
