Regarding ping during the test, although it isn't ideal, it appears
to be enough to identify problems, and also consistently get the same
grade, to within one grade level anyway.
An "A" or "A+" is not going to get a "C", and a "D" or "F" is never
going to get a "B" no matter how many times the tes
1 probe per second IZ not enough for science! (see my forked thread)

In one of the threads I saw that the dslreports test is one http ping
every second. I am not really sure how that is handled - if the
connection is
tcp (?) and persistent, that measures 1 packet RTT, if it is a new
connection, it is quite a few RTTs.
And it is really not enough pings for valid sta

Thanks, that is exactly the information I was looking for. Given that,

Each bar is an individual probe they go out once per second, which
determines their
position along the X-Axis, and are tagged by color *when they come back*.
For the radar plot, the ones showing latencies to each location, it is
nothing to do
with buffer bloat but there are two green colors super-
Hi Jb,
I wonder the ping RTT plot, does it show all individual RTT-probes, or is it
showing an aggregate measure per bar? If aggregate which measure (hopefully the
maximum or something close like a high percentile)?
Best Regards

It gives my connection an "A" in both directions :)
Which would be incorrect as it is a definite "D" or worse.
But it is hosted in the UK, and uses a single stream, so it doesn't fill
the pipe.
If it can't fill an 8mbit connection it is going to be misleading - unless
you are very close to them.

I think there will always be the occasional incorrectly graded test,
this one is simply because the median of the downstream latency
ignores the spike. If I used average(), then it would not ignore
the spike, h
