I was confused; the thing that = lingered at the back of my mind was that if we do the target extension for = one direction and correct the interval in that direction, we should also co= rrect the interval in the other direction, especially since as Jonathan poi= nts out the interval describes the full back-and-forth path=E2=80=A6 > > Best Regards > Sebastian > I've updated the target to be 22ms based on my current interval of 450ms. http://www.dslreports.com/speedtest/4523668 It's not pretty, but the quality is A or A+. It's interesting to see the saw tooth pattern for the upload. This was not the case when the target was 5ms, which I believe was calculated based on a 100ms worse rtt.
