This text explains why traditional, standardized golf models fail: they ignore a player’s Intrinsic Dynamics — the natural movement blueprint defined by joint structure, arm behavior, and rotational tendencies. To create truly individualized coaching, the system introduces the 3x3 Swing Archetype Model, which classifies golfers using two core elements: Upper Body Types (arm and shoulder mechanics) and Lower Body Dynamics (pelvic rotation and the key biomechanical value known as the sway gap). The model is supported by the AI Golf Chatbot, which provides real-time 3D data across more than 35 parameters.

The matrix shifts instruction from a correction-based approach to precision-guided improvement. Many so-called swing faults are simply mismatches between the player’s technique and their physical design. Once a coach understands a player’s intrinsic movement patterns, the golfer no longer works against their own body — a crucial factor for consistency under pressure.

The Upper Body Types include:

• On Top: Shoulder-dominant movers with deeper hand paths and a steeper transition.
• Under: Forearm- and elbow-driven movers with strong forearm rotation and a naturally flatter shaft.
• On the Side: A neutral blend of arm and shoulder motion.

The Lower Body Dynamics are defined by pelvic rotation and the sway gap, the lateral distance between the chest and pelvis centers.

• Large sway gap (≥8"): Linked to in-to-out paths and draw patterns.
• Small sway gap (≤4.5"): Common among players who produce fades or cuts.

Combining both systems creates nine complete swing archetypes, each with specific matchups for grip, setup, shaft pitch, and rotational strategy. A player with an “On Top” pattern requires different drills than an “Under” mover; using the wrong drills creates instability and limits performance.

A major strength of the matrix is long-term safety. Forcing mechanics that contradict a player’s natural blueprint leads to overuse, inconsistency, and burnout. A swing built in harmony with the body becomes more efficient, powerful, and repeatable.

The sway gap also acts as a precise indicator for rotational efficiency:

• Setup: 2–4" is considered neutral.
• Impact: The gap strongly predicts shot shape (draw vs. fade).

Overall, the 3x3 Swing Archetype Matrix treats the swing not as an aesthetic model but as a biomechanical identity, making instruction more accurate, sustainable, and body-compatible than any traditional teaching method.
