Actually, I've been reading up on it.
OCCASIONALLY it hits the 400 area, but most players stay in the range of 200 - 300.
Also, lets keep in mind that with star craft, your constantly clicking the mouse because there is a LOT more management to do, And sure I could stay in one place and shffl shine nairs in one spot for the entire 3 minutes of a melee match, but my opponent would hit me for it.
If we can get a smasher that could actually just sit on fd and shffl shine nairs for 3 straight minutes we could get an accurate count, if anyone can do that, and record please do.
