Beyond Flow: Decision Clarity
Mihaly Csikszentmihalyi described flow as total focus on a task. It is felt inside, so it is hard to measure from outside.
The Decision Clarity Window splits flow into four signals on video. Peak clarity is when all four rise above a set line at once.

The Four Indices
Attentional Stability Index: do the eyes hold on a target? Processing Efficiency Index: blink patterns, which shift with mental workload. Focus Quality Consistency: does attention hold? Expression Quietness: how little the face moves in hard moments. It describes the face, not a feeling.
When all four hold for 15 frames or more (about half a second), the system logs a window. The share of the session in it is the score.
Peak performance is a high moment you can hold.
03
Why This Matters for Performance
Peak performance is a high moment you can hold. One person holds it for 45 percent of a session, another for 12 percent (an example, not a result). A frame-by-frame read catches the hold.

Practical Applications
Coaches see which athletes stay clear in big moments. HR leaders track it through coaching, as one sign the work lands.
