Personally I might be skewed by using Firefox on Linux, I don't see the 
awesome live bloat-meter, only the awesome bloat graphs.

PS My firefox also doesn't show the new graph-based speedtest history.  
I disabled the obvious culprits (noscript, ghostery, ublock) & there's 
nothing on the JS console.  Happy to help if needed.

"Fixing" the bufferbloat ping graph would make it more directly 
comparable to the pings on other speedtests.  I think that makes the 
bufferbloat point clearer.  Again the issue is outside the US; in the UK 
I see a 100ms "baseline".  If it's simple to start using nearer servers, 
that would make me very happy :).

I agree it's not "broken".  (I also use netperf-eu at 59ms).  It's just 
confusing to interpret, if you don't already know what bufferbloat is 
going to look like.

Particularly as the "expected" low ping value shown at the start. The 
100ms server isn't even shown on the ping radar part.

If it's easier to just call out the destination country on the 
bufferbloat ping, or fudge the figures convincingly (just graph the 
increases from a minimum), that would answer my point too.

Thanks
