title: Does having variations of gestures in gesture library improve recognition?
body: <p>I'm working on implementing gesture recognition in my app, using the Gestures Builder to create a library of gestures.  I'm wondering if having multiple variations of a gesture will help or hinder recognition (or performance).  For example, I want to recognize a circular gesture.  I'm going to have at least two variations - one for a clockwise circle, and one for counterclockwise, with the same semantic meaning so that the user doesn't have to think about it.  However, I'm wondering if it would be desirable to save several gestures for each direction, for example, of various radii, or with different shapes that are "close enough" - like egg shapes, ellipses, etc., including different angular rotations of each.  Anybody have experience with this?</p>
