Average View Time represents the average number of milliseconds people played per session.

It's essentially the total sum of `PLAYED` vs the count of `IMPRESSION_ID`.

### Aggregation limitation

The average view time metric is currently limited to only support the `AVG` aggregation. It therefore cannot be queried as a `median` or `sum`.

The sum of the view time is equivalent to the [total hours watched metric](🔗)
