The WC chain punches is another good example. If you use "forward pressure" (that mean's your body is not rotated) and try to throw 4 straight punches in 1 second (or even faster), when and how will you be able to generate your power for each punches? You may generate 1 powerful punch for every 3 non-powerful punches. To me, that's to use 3 fake punches to set up a real punch, it's no longer chain punches by definition.
