Session tools

Best logic (what “Best” means)

Runs table: stays in run order so you can audit sequential changes.

Best 10: sorted by lowest CdA first (what the athlete sees).

QC: displayed as a quality signal; use “Best10 A-only” to filter to A/green.

Best10 score: a separate ranking signal (not always identical to lowest CdA).

Benchmark run

Reference run for measuring position gains/losses. Use the most consistent, representative run from this session.

Best (lowest CdA): #199

Baseline guidance

Prefer: QC A, high included distance, consistent laps.

Avoid: power dropouts, many excluded laps, heavy selection edits.

Rule of thumb: top Best10 run you would trust in a report.

Math & inputs (transparency)

What the report is comparing

Charts and text compare Baseline vs Best10 (top-ranked run). If Baseline isn’t set, the report can’t show baseline-vs-best context.

The “Ref @XX” selector picks the reference speed used for some headline comparisons (e.g., P@Ref / time savings).

For exact solver inputs, open any run and check its Solver summary.

CdA rank is computed across runs with valid CdA (lower is better). Ties break by more included meters. · Best10 score is an internal ranking score (higher is better) used to pick Best10.

B Best CdA Why MANY_UNSTABLE_LAPS Many unstable laps: focus on smoother pacing and consistent position; exclude visibly noisy laps and avoid wind gusts. LOW_CONFIDENCE Low confidence: steady effort/position, avoid gusts/surges, verify 1s recording + no power dropouts. UNSTABLE_POWER Power instability: smooth power delivery (no surges), check power sensor zero-offset, and watch for dropouts/spikes. POWER_VARIABILITY Power variability (not dropouts/spikes): pacing is inconsistent in the chosen section; aim for steadier power and fewer surges. Recommended next steps: Include QC reasons Copied Choose the cleanest contiguous window; reduce selection to exclude obvious disturbances. Verify recording is 1s (not smart recording) and that power has no dropouts. Check power meter calibration/zero-offset and look for hidden dropouts/spikes. Re-test with steadier pacing/position; add laps until instability is diluted. Prioritize a truly steady section: same position, no braking/traffic, no surges. If wind is gusty, repeat in calmer conditions or add more clean laps. Target constant power (avoid micro-surges); use a pacing target and smooth pedaling. Pick a steadier pacing target; avoid surges between straights/corners. If variability is structural (course/traffic), choose a better time/location or add laps. conf 0.59 • rej 0% • unstable 1	#199 2026-05-07 19:37:38 analyzed	Run 199 Setup: — Next: Add in Setup → Change notes (what to try next).	2642 m 1 laps	1.1570 T 19.0°C • P 964 hPa • RH 68%		0.2843 ΔCdA +0.0000 · ΔW@45 +0 CdA rank 1 Best	373 W P50 501 W	Ref — 35→188W 40→270W 45→373W 50→501W 55→656W	96.0	Open
