1. Understanding the differences in styles of leadoffs. Statistically, the track style gets called out more often than the traditional style. The umpires is seeing movement, which doesn't mean the runner has left the bag, (queue the
daddy-pires yelling from the parking lot. Oh, did you get a good view of that from 1/4 mile away after eight beers?)

2. As far as batter's box, outside of the box is fine, if there is indeed a box. If there isn't a box, you have no idea. It becomes outside of the imaginary box.

Just like the pitching rules. When people complain about the pitcher doing this, or the pitcher doing that, just hit the damn ball.
