# MICROSTUDY B

This folder contains the refinement microstudy following `Study 000A` and `Study 000B`.

## Why this study exists

The flagship studies established selective adaptation and a mixed internal-cost profile. This microstudy asks whether a higher stabilization-demand proxy clarifies how cadence and stride were allocated.

## Headline findings

- All 8 outdoor QC-pass runs averaged 5.19% cadence residual and -7.14% stride residual relative to treadmill-expected values.
- The later specialized outdoor subset of 5 runs averaged 11.15% cadence residual and -10.58% stride residual.
- Vertical ratio was above treadmill-expected values in 5/5 later specialized outdoor runs.
- The later outdoor vertical-ratio pattern appears more consistent with suppressed stride expression than with increased vertical oscillation.
