How is this calculated?
We sum the duration of every video in the playlist. Private or deleted videos have no duration and are counted separately.

Up to 500 videos on the free tool. Each page of 50 costs one unit of our daily API quota.
Does it save anything?
No. Results are cached for six hours by playlist id and then dropped.
