Because anyone who's curious can go to that page and read it?

No, that can't be the reason, must be that I'm trying to hide the
truth. Or something...

Beezarre. The fact that there was more than one line in my post,
with some information here and some there, somehow shows...
well I'm not sure what your point is, but it's very strange.

>Here readers can see that you have phi(x,x) *defined* by pi(x) and
>pi(sqrt(x)), 

Uh, no, that's not the definition of phi(x,x).

>which may be what David Ullrich apparently thought was

I was "hiding" this formula by providing a link to that page.
Right.

And it's clear to anyone but you that that's exactly what I did.

Not sure whether it's clear to you or not. Could be you're stupid,
could be you're lying, as always it's hard to decide.

Exactly where did I state that I'd presented all of Legendre's
method?

Hint: All I presented was the part that was needed to show
that your statement about how your formula was the first
in history to count primes via a difference equation was false...
