From the curve to the next test
The curve guides what the AI changes.
- 1
The player measures
How much of the video each person watched with sound on, counted on the video's real time.
- 2
The curve shows the drop
Where retention falls hard, where the pitch is and where clicks happen.
- 3
The AI acts on it
Button timing and the bar's pace are tested based on the curve.
The points that decide the sale
- Retention across the videoHow viewers drop off through the video, in real time, not the progress bar's time.
- Reached the pitchHow many people were watching when the offer started.
- Click zoneWhere button clicks cluster.
- The same data the AI usesThis is the curve the AI uses to test the button timing and the bar's pacing.
Retention counts people watching with sound. Someone who stays on muted autoplay and leaves isn't in the curve.
