Haven't taken the test, but that's because my reading speed varies based on subject matter and authorial style, so I doubt there's a test that could properly analyze it. However, if all I'm doing is reading (like while I'm in the tub, say), I can read maybe 150 pages on average in an hour--and my comprehension is so good that I tend to spot continuity errors.
