  == flip trick legend ==  I propose clearing a legend for the flip tricks.  It would look something like this:  Board Flip: Board Spin: Rider Rotation:  The flip field would have a heel/kick flip value, spin and rotation would have a frontside/backside value, all would have a degree value, and would be measured as compared to a stationary observer.    ex: 360 Flip     (text description)  Board Flip: 360 degrees kick Board Spin: 360 degrees backside Rider Rotation: none  Big Spin: (text description)  Board Flip: none Board Spin: 360 degrees backside Rider Rotation: 180 degrees backside   Or it could be broken down into parts of the trick:  Underflip: (text)  Part 1: Board Flip: 270 degrees kick Board Spin: none Rider Rotation: none  Part 2: Board Flip: 270 degrees heel Board Spin: none Rider Rotation: none
