TV watching to record data: a good idea?
Let me tell you what I’ve been meaning to do. I have Dennis Martinez’ perfect game on DVD (Dodger Stadium). What I’ve been wanting to do, for a long time, is the “perfect” sabermetric scorecard (to go with his perfect game). So, record EVERYTHING that happened, and I mean everything. If he grabbed his crotch, I’ll mark it down. When he fell to his knees to field a bunt, I’ll note that, with a timestamp, location, and his arm angle as he threw to 1B. Basically, I was going to allow myself to become sabermetrically insane for 9 hours (because I’ll be pausing the game alot).
Anyway, pitch location. I was going to mark where the ball, AS SEEN FROM DODGER CF TV, hits the plate. I am NOT going to mark where I “think” it went. No. I’m going to mark where it actually went from that angle on a 2D TV screen.
This is what I’m thinking, and tell me if I’m wrong:
- If the Dodger CF TV was positioned back then as it is today, then:
- I should be able to mark a Dodger game on TV in 2011, and compare it to PITCHf/x
- I will then have a “translator” all setup, to link where I saw the ball hit the 2D TV angled picture to what PITCHf/x recorded
- I would then be able to reverse-engineer Martinez’s pitches as if PITCHf/x had marked its location
So, that’s the benefit to marking the TV location.
