Instead of using the mode of discrete build times directly, Tor clients compute the Xm parameter using the weighted average of the the midpoints of the 'cbtnummodes' (10) most frequently occurring 10ms histogram bins. - Ties are broken in favor of earlier bins. + Ties are broken in favor of earlier bins (that is, in favor of bins + corresponding to shorter build times).
(The use of 10 modes was found to minimize error from the selected cbtquantile, with 10ms bins for quantiles 60-80, compared to many other
