dougies, I gave you the answer. read it again. And again, if you need to.
And again. And again.

Let's see, did I post a bit of further explanation after Jax fell
short on tip vortex? It's in my "sent" file. Or did it go right over
your head?

didn't know any more about vortices that you do.

In other words, you don't know the answer and now you're running away.
But why are you running away so soon, Jax? Losing confidence in your
MENSA power?


(do keep in mind, dougies, that *neither* you nor he knew that the plural
of
vortex is votices)

Both 'vortexes' and 'vortices' are listed as correct in my dictionary.
But when you don't really know anything about a subject, you quibble as
strongly as you can (which in this case, ain't very)
