In the case of a videoconferencing application, what matters most is max jitter, where the app will choose to ride the top edge of that, rather than follow it. I'd prefer using a 98% number, rather than 75% number, to weight where the typical delay in a videoconfernce might end up.

[SM] Maybe the solution would be to increase the frequency of the RTT measures and increase the quantile somewhat, maybe 90 or 95?
