Why do FP games last so long

[bkbjones]

Didn't want to do my usual thread hijacking.
Mike brings up a good point in another thread. FP games usually last longer than SP games. As he said, 20-30 minutes in many cases, sometimes longer.

Why?

There are many reasons, obviously. There are also many ways to speed things up.

One of my pet peeves is batters wandering out of the box on "plain vanilla" balls and strikes. This is not just something we deal with up here in the Pacific NW. I've seen it in other parts of the country, and seen it for years. Keeping batters in/near the box is just one way. Are there others?
