How close to perfect is Stephen Curry?

The Wall Street Journal asked me to analyze a bunch of Stephen Curry's three-point shots.  Wow, was that fun!  Curry is about as pure a shooter as I've ever seen.  His motion is fluid and his release time is shorter than any other shooter I've analyzed.  More details may be found in the Wall Street Journal article here.  If you've not looked carefully at Curry's shot, click here for a YouTube video.  The guy is smooth as silk!
