When pressing "D" within MTR, one sees a "Last n pings" side-scrolling output. At the bottom is a scale with the different max-times. I understand how this relates to the scrolling data.
Scale: .:1 ms 1:4 ms 2:10 ms 3:17 ms a:28 ms b:40 ms c:54 ms >
How is this scale calculated? Periodically, it will change to reflect, I assume, new data. My guess is that it has to do with distributions of response times and that each level would represent a certain percentage.
I'd like to be able to look at the scale and say "95% of packets are returned within 28ms" for example.
How is the scale arrived at?
