Works when loading a > previous data file as well=E2=80=A6 Ah, now git pull acyually got me something new and without a -p = directive I also see the stats output, great! Now I actually do wonder = how hard it would be to add a measure of variance, say the standard deviation or the standard error = of the mean to the output (to qualify the average, which probably is the = arithmetic mean, which might be worth noting in the header column). And = finally for the latency probes, I believe maybe the 95th or 99th = percentile would be closer to what we recommend people looking at? (I = note that I typically start my flent runs with 10 un-contended ICMP echo = requests from the command line to get a reasonable idea what the best = case RTT actually is, a similar value could be extracted from the start = of the flent run before the data streams have started?) I guess instead = of writing emails I should actually look and write code=E2=80=A6 (maybe = I find tie to look into that). Final questions why is this output = mutually exclusive with plots?
