Fires when days_since_last_race > 30. A layoff of 30 or more days introduces genuine uncertainty about a horse's current physical condition, fitness level, and readiness to run a competitive race. Layoff horses win at below-average rates on average, though the sub-angles RETURNING_WITH_WORKOUT and RETURNING_WITH_BULLET can partially offset this concern. This flag is informational as much as negative — it signals that the handicapper should verify workout activity and look for other readiness indicators before committing.
