Comment(by mikeperry):

 I think the way we want to do this is simple multiplication. Assuming the
 bw auth ambient failure really is an accurate measurement of the network-
 wide failure rate, then the adversary needs to fail 1.0-c/n of the
 *remaining* successful circuits in order to capture those routes.

 Therefore, if the bandwidth auths publish a weighted circuit success rate
 as wcirc_success, the dirauths can just multiply the initial path bias
 numbers by this wcirc_success value to get new values for the consensus
 parameters pb_noticepct, pb_warnpct, and pb_extremepct.
