very true, I just thought it was a little fun thing to talk about. As a rule, I'm pretty slow all around, because i take time to try to pull in relevant details...however, apparently I don't do a very good job of it, judging from my "comprehension" score. Though, maybe a better term for that would be 'retention.' I, too, "comprehend" (understand) what I'm reading, but, like you, didn't retain it very long
I've searched around and come to the conclusion that "fast" would have been just fine in an adverbial usage in the thread title. In fact, i think it sounds better. I don't know why I got hung up on that, really.
