Btw it actually is a myth that the K zone increases with two strikes (unfortunately even propagated in the article). Strike zone gets smaller with 2 strikes and bigger with 3 balls. Umps don't like to end at bats.

I think the stat guys forgot to consider that takes are much rarer in the zone. Z swing rate is more than twice as high as o swing rate so there are simply more chances to have false positive strike counts than false positive ball counts
