This might be interesting to you as well, if your pedals are new (also from the manual):

"With conventional pedals, if the spring tension is set low, then it's easy to unclip but also easy to accidentally pull out of the pedal. If the spring tension is set high, than you won't accidentally pull out of the pedal but it's also very hard to clip in or out.

"The unique patented Eggbeater desing eliminates the need for spring tension adjustment. Retention is not dependant on spring tension. Clipping in and out will become easier after the cleats break in."

I would say this is true, actually. It does get easier. It's not dramatic, it goes from being a very crisp motion to being, er, a somewhat flaccid motion, but it does get "looser" feeling.
