1. The Core Problem Zwift 12-Week FTP Builder 2026 Solves
Most teams / athletes / developers fail on cycling not because they lack tools but because they skip 3 decision gates. In this article we map each gate with a pass/fail checklist so you can audit your setup in 12 minutes.
1.1 Decision Gate 1 — Baseline Measurement
- Define 3 objective KPIs, not 1 subjective feeling.
- Collect 7 days of baseline before any intervention.
- Record confidence interval (5th/50th/95th percentile).
2. The Step-by-Step Playbook (9 Actions in Priority Order)
- Freeze your environment / equipment for the length of the test.
- Introduce only ONE variable each 7-day cycle.
- Log delta against the 95th percentile of baseline.
- Reject any change with a negative 5th percentile delta.
- Document the protocol in one shareable page + screenshots.
- Ask a teammate to spot-check 10% of the logs.
- Run A/A sanity test every 4 weeks on the baseline tooling.
- Hand-off checklist: pre-cond, steps, expected delta, rollback.
- Archive results to org-wide library + tag with 3 keywords.
3. 9 Common Pitfalls and How to Escape
- The "Hurry" trap: skipping baseline → all deltas look like noise.
- Multiple variables → you never know which caused delta.
- Outlier cherry-picking: quoting best-case instead of P50.
- Survivorship bias: drop-outs not counted.
- Confirmation bias: stopping when delta matches belief.
- Measurement drift: tool / scale not calibrated weekly.
- Fractional attribution math error (100%+ delta explained).
- Small-N: statistically meaningless (<30 runs).
- No rollback plan: bad change cannot be undone in <10 min.
3.1 Priority 1 — What You Can Automate Today
- Data collection, dashboards, and 95th percentile reporting — automatable via Korelyy.
- Spot-check audits, rollback approvals and ethics sign-offs — human gate.
