Why it matters
It shows exactly where people leave, which is where your next fix is.
Example
A sharp drop at second 2, then a flat line: the hook lost people, the rest held.
Common mistake
Only looking at the overall average instead of the shape of the line.
How to use it
Every graph starts dropping, so look for the shape. A steep fall in the first few seconds means the opening didn’t make a clear enough promise. Gradual sliding means pacing. A sudden cliff points to one moment: a slow explanation, a cut that confused people or an early payoff. A bump means people rewatched something, which is worth doing again.
