What You See
Shows your 'Structural Identity' (a label describing your runner type). Below are insight cards with a title, description, a status badge (Observational, Emerging, or Supported), and a confidence bar showing how sure PIRX is about each insight.
How the Numbers Work
PIRX analyzes patterns in your training history to detect recurring behaviors and their effects. Insights start as 'Observational' when first detected, move to 'Emerging' as more evidence appears, and become 'Supported' when the pattern is confirmed across multiple weeks of data.
Step by Step
Method used: rule-based pattern checks on your own training
- PIRX reviews your recent training blocks on a schedule.
- It keeps a pattern only when the same training signal and the same projection move show up together across weeks.
- Zone mix is labeled from your own zone proportions: Polarized, Pyramidal, Threshold-Heavy, or Mixed. The label you see most often is your Structural Identity.
- Confidence tiers: insights start as Observational (1-3 weeks of evidence), advance to Emerging (4-6 weeks), and reach Supported (7+ weeks of consistent signal). The browser maps these tiers to progress bar width: one-third, two-thirds, or full.
