It's the kind of thing nobody pays attention to.

For example, we can set a different CK taker for left and right corners. If your CK specialist is left footed and happened to succeed in 7/10 attempts on the left and 3/10 from the right... Nobody would have tracked it to see the huge difference. We all will just be content to say he made 10/20 attempts total. Nobody (except Al's training research) talks with this level of precision about our tactics. Unfortunately.

We aren't given a lot of stats, hard numbers to work with, so anything at that level takes personal motivation to try to observe.
