The threshold in time-based loss detection is a reordering threshold, not an absolute delay threshold. The path has to have both reordering and high delay variability... I'll grant that that is certainly possible. The experience we have so far is with this particular algorithm, which does not incorporate variance.

I'm not opposed to incorporating the variance into the delay metric, but I don't think we know what the right answer there is.  We could add a note that discusses variance and that we need more data on how to do this right.
