You're accessing 78% of your cognitive capacity today. Recovery is your limiting factor.
The Primacy System in 2 Minutes
See how the Primacy system turns complex data into clear, actionable insights for cognitive optimization.
Intelligence Becomes Action
Your calendar knows your commitments. Primacy knows your state.
“Your recovery is strong at 88%, but cognitive access is at 65%. Your bottleneck is focus availability, not energy. You're prone to distraction after 90-minute work blocks.”
- Protect the 30 minutes before your 10:00 call — no inbox, no Slack
- Lead with the prepared deck; today is not ideal for improvising new strategy
- Sequence analytical work before meetings; leave admin for the afternoon
Your Foundational Advantage
Peak performance isn't about working harder—it's the product of cognitive capacity and recovery. Primacy measures both sides of this equation, interprets the data and delivers the insights you need to optimize it.
Willpower is limited. Direct it with intelligence.

Cognitive readiness, synthesized
Your executive summary. Primacy synthesizes sleep, HRV, cognitive tests, and physical load into a single snapshot—so you can assess your mental resources at a glance and deploy them strategically.
Cognitive Access45%
Your Available Cognitive Horsepower. What percentage of your total capacity is online today? Measured directly by the DCTT against your PFTT ceiling.
Recovery40%
Your Resource Base. Is your foundation solid or depleted? Combines sleep quality, HRV, and resting heart rate.
Drive15%
Your Willingness to Engage. A daily self-check — low drive penalizes more than high drive rewards, reflecting real motivational dynamics.
Physical LoadModifier
Your Strategic Context. Is yesterday's training fueling or draining today's mental performance? Scales the combined score ×0.85–1.08 via hormesis.
