TrailGenic’s practice of recording multiple interacting movement, environmental, and metabolic conditions within a session.
Stacking describes exposure, not proof of synergistic or greater-than-additive benefit. Record each available component and its timing. When fasting, altitude, heat, terrain, and duration change together, the response cannot be attributed to any one component without a suitable comparison.
Keep context, behavior, recorded response, follow-up, and interpretation distinguishable. Ella examines longitudinal patterns and alternatives; a decision rule remains dated and revisable.
