I think many people are too concerned with rate of fire. Now don't get me wrong, there are instances where the faster the better, but for the most part, it's not going to make a huge difference if you're shooting 5 or 8 or 14 bps.
Now, back on topic, it does look foolish, yes, but then again, if that's what it takes to win, that's what you'll have to do. There is a better way though, just walk it.
