+ - Alter calculation of Pareto distribution parameter 'Xm' for
+ Circuit Build Timeout learning to use the weighted average of
+ the top N=3 modes, because we have three entry guards. This should
+ improve the timeout calculation in some cases, and prevent extremely

+ on the Pareto CDF or 60 seconds, whichever is greater. This is done
+ to provide better data for the new Pareto model. This percentile

what should go in a patch.
