Capacity fingerprint

Each ridge is one dimension of capacity: its distribution over 38 days, your baseline (tick), and where you sit right now (red marker).

{{ rg.name }} {{ rg.delta }} Lower range Upper range

Pattern with the strongest evidence: you recover quickly from short cognitive strain, but prolonged sessions create a delayed recovery cost later in the day. Based on 41 sessions. Repeated personal pattern, not a controlled result.

Milestones

{{ ms.d }} {{ ms.t }}

Every session narrows the model. Brink began with a population baseline; 38 days later it predicts this person's decline onset within ±4 minutes, knows which of 14 tested interventions work for him, and has 6 reliable personal patterns it can act on.
