Comparable-run evidence

Inspect the pattern. Know what it is made from.

The chart and evidence ledger now sit together. Units, comparison basis, source type, and uncertainty remain visible in one spread.

Lieflat F2 / Hairline Line

Twenty-eight comparable runs

Illustrative comparable-run series Twenty-eight dated run points. Hollow points denote runs dated on a weekend. Two separated peaks are labelled.

Illustrative efficiency ranges from 1.31 to 1.48 metres per heartbeat across 28 comparable runs.

One dot = one run · hollow = weekend date · demo data, not an athlete result

The chart exists to change a decision.

Test a conservative next-load scenario. The recorded example stays fixed; only the clearly marked illustrative projection changes.

Lieflat F3 / Hairline Area

Daily training load

Illustrative daily training-load history and projection Forty-five daily hairlines. The first 28 are an illustrative recorded period and the final 17 are a selected projection.

Maintain keeps the illustrative seven-day average near 52 load points.

One hairline = one day · dashed = projection · arbitrary load points

Your record.
Your decision.

Aerithm is local-first today. Material plan changes remain proposals that you can accept, reject, or undo.

No remote model training
No remote language model receives athlete data.
No silent plan changes
Material changes require athlete approval and retain an undo path.
Missing stays missing
Absent evidence is shown as unavailable, not converted into false precision.
