<div><br>Apparently I shouldn't send e-mails quickly, as it comes out as gibberish. It was the first 10000. The thirteen seconds was just approximate, but it showed the C one was much faster, which I figured was because I had constructed it poorly. Apparently I had, and I even managed to type it in wrong.
