Catcher Spotting: Measuring Pitch Precision

This is an effort to record the intended target of pitches in Major League Baseball through the position and visual cues of the catcher. We first need to measure how differently people will record their perceptions, by having a large number of people record up to 3 innings of the same game. We would especially like volunteers to record the 4th through 6th innings of ALCS, NLCS and World Series games!
