As a general rule, I've seen a trend as officials develop; I've seen it in myself as well.

1. New officials unsure what to call, not blowing their whistle.
2. Start seeing plays better, start calling everything.
3. Realize not all contact is a foul, start looking for advantage and end up letting too much go.
4. Judgment improves, and they get closer to reaching a proper balance.

The length of time through each stage varies, obviously. Also, obviously, the off-ball awareness develops independently of (but similar to) those four stages.
