'The average latency of all tests performed in the tile, represented in = milliseconds' This is infinitely better than no under-load numbers. However, the = latency distribution is neither 'normal'* nor fully symmetric (it can = not, there is a hard minimum, the minimal path RTT and a hard maximum = (icmp timeout) even though the distribution will likely be closer to the = minimum than the maximum)**. Next improvement possibility: they report averages and number of tests, = but no measure of variance...=20 To put a positive spin on it, reporting luli numbers at all is great, as = is the potential to improve the reporting quality with small additions! Regards Sebastian *) Which is not a showstopper per se as long as the distribution is = unimodal and not too skewed then the average is still intuitively = interpretable, but is it? **) My gut feeling is a beta distribution could be fitted to the data = and that functions control parameters reported to better model the = expected distribution shape. P.S.: This time without links to test what triggers getting blocked...=
