| Watch time is defined as the amount of elapsed media time for audio+video |

| Any one of paused, hidden, or muted is sufficient to stop watch time metric |
| reports. Each of these has a hysteresis where if the state change is undone |
| within some time, the watch time will be counted as uninterrupted. |

| Power events (on/off battery power) have a similar hysteresis, but unlike |
