Differences by Developmental Stage

【Early Stage: Individual Use Period (Childhood to Early Adolescence)】

Takes time, externalization needed
Strengthening: Diverse inputs (-Te-p), diverse outputs (+Si-c)

【Mid Stage: Easy Coordination Period (Late Adolescence to Early Adulthood)】
Coordination becomes easy, "hacking while caring" becomes possible
Instant hack -> immediate sustained care
Strengthening: Diverse thinking and reflection (Correlator)

【Late Stage: Integration Period (Late Adulthood to Middle Age)】
Gradually blending, formation of vortex synergy
Unified as "maintenance and continuity"
Improved intuitive accuracy through experience

【Mature Stage: Complete Integration Period (Middle Age to Old Age)】
Finally becomes one process
