The speed of what, exactly?

Who, precisely please, in this forum, ever said such a thing?

This part of the quote is probably the most apropos statement with regards
to follows-up to your posts.

OK, I've asked three simple questions. Do you have what it takes to simply
answer them, without the troll's recourse to obfuscation, misdirection, and
insult? I bet not. After all, you're still unable to stop top-posting.
It's such a simple thing, really, yet you're not able to grasp the concept.
