1 in 5 wrong? Really?

[mbyron]

It was my understanding as well that the claim is 20% wrong of the 1.3 "close calls" per game. If we say that's .25 of a blown call per game on average (not just outs, but fair/foul, above the HR line/below the HR line, etc.) that's one blown call for every 4 MLB games.

Apart from the fact that that number is ASTONISHINGLY low just in its own right, the question is whether it warrants more replay. One argument that shouldn't fly any longer is that more replay would slow down the game: if replay were targeted at the 1.3 "close" calls each game, it would have no significant impact on the length of games.

That said, I'd still like to know how many of the "close" calls really affected the outcome. Apparently the downside of adding more replay isn't so bad; but what's the upside, really?
