Until recently, you could get close to 99% just by counting requests for favicon.ico. And then the mobiles came out. Some ask for one of the eight variations on "apple-touch-icon",* some don't.

humans can't read 30 pages a minute, or 3 pages in a second
And conversely: If there are requests for associated files like images, humans will get them all in a lump, as fast as the server will deliver them. Robots tend to space their requests evenly, regardless of filetype.
If it's a human on a satellite connection, all bets are off.
* If you have two of the eight, it will ask for one of the other six.
