Have the people that are saying things like this tested it themselves? Just looking at his hand it looks slow but when you think about the number (16 taps per second) it seems amazing. I'm not saying anyone here can't do this faster than Takahashi, I'm just asking. I also have been using the vibrating technique in games, and to change TV channels, but I'm not willing to say I'm faster than Takahashi because I have never tried one of those myself.
And of course, video is the only proof.
EDIT: He reminds me of George Foreman. He's the lean mean button-mashing machine!
