How did Tom do?
I did better than 99% of all the test takers in most categories.
My computational speed really pulled the curve down on my results. I only did better than 42% of all the test takers! Guess I'm "slow." Nothing a bit of cybernetics couldn't solve. My geometric and spatial scores are the stars of my intelligence. (pulls suspender straps out by the thumbs)

While speed cannot be the sole factor in determining overall superiority in one mental operations, in general faster computational speed will often indicate that a problem's comprehension was more complete. With everything else being equal, a person with faster computational speed than another person's will be better at tasks that require the synthesis of many bits of information."
