Yeah, that's pretty much what I'm getting out of the article... the problem is I still have no idea what that scale is, do you? I'm sure the term 'supersonic' was meant to impress and sound fast, but there's at least an order of magnitude uncertainty.

> "Sound" itself needs careful definition in such atmospheres.

Nothing to say here except I love that sentence.

I could hazard a guess, but I doubt the scientists have particularly precise measurements (and if they did they'd be better found in a paper rather than my guessing). Having a number and concentrating on it misses the forest for the trees, it's a big number, but not the most interesting part by far.
