Explanation

Multiply by 0.25 because 1 s/400m maps to 0.0025 s/m and 1 s/100m maps to 0.01 s/m.

Method & Pace Basis

Method basis: fixed split-distance definitions normalized through seconds per meter.
Applied factor: 1 Seconds per 400 Meters = 0.25 Seconds per 100 Meters.
Consistency rule: calculator output and common-value rows use the same seconds-per-meter pace basis in both directions.
