If you're saying Chien-Ming Wang's sinker has lost many inches of movement,
you'll also have to say he used a screwball in 2008.  Or you can just say
that Yankee Stadium was wrong in 2007, adjusted too much for 2008, and again
at the new park in 2009.  Based on the slider movement, it's still off.

That makes it hard to tell what's changed with Wang without adjusting the
base data.  That includes the release points, the initial acceleration and
velocity values.

Bonus graph: lateral acceleration (ax) from Yankee Stadium(s) from 2007 thru
2009.
