One might respond, well, technically, I suppose we don't want to consider using CAT5 at all, but we'd like to compare the technology we're going to use with the previous technology, to see how much better present technology performs.

For years I'd try to follow search parameter advice, meaning using as few terms as possible that relate EXACTLY to what I'm looking for. Meanwhile, google got better and better and now you can write a question just as you'd ask it. Of course, that doesn't mean our question-asking skills have advanced while google has gotten better....
