This framework outlines the philosophy of Danish instructor Henrik Jentsch, whose teaching shifted golf instruction from swing aesthetics to impact physics. His central maxim — “The Ball Never Lies” — replaced model-based swing ideals with objective ball-flight analysis. What matters is not how the swing looks, but what the clubface delivers at impact.

From Positions to Impact Truth

Traditional instruction focused on static checkpoints. Jentsch reversed the process. He analyzed start direction, curvature and spin to diagnose impact conditions. Instead of prescribing ideal positions, he worked backwards from ball flight. A swing could look unconventional yet function perfectly if the face-to-path relationship was correct.

Feel vs. Real

Jentsch addressed the gap between what players feel and what actually happens. Ball flight became the final judge. His descriptive model relied on measurable reality rather than instructor opinion, adjusting only what influenced impact variables.

Biomechanics and Ground Forces

His work integrated kinematics and Ground Reaction Forces. Power originates from pushing against the ground (Newton’s Third Law). Faulty ball flights often reflect breakdowns in sequencing — inefficient energy transfer from ground to torso to club. This body-driven model replaced hand manipulation and anticipated today’s launch monitor era.

The Ball Roll Laws

Applying impact physics to putting, Jentsch reframed putting as collision science. The key variables: launch angle, side spin, skid phase and true roll.

• Minimize skid, maximize immediate forward roll

• Eliminate side spin through square face-to-path delivery

• Fit loft, lie and weight objectively to stroke mechanics

Using high-precision 3D systems, putting became measurable rather than mystical.

The 2026 Golf Manifesto

Jentsch introduced four strict scoring rules designed to remove emotional decision-making:

1. Fairway First – If you don’t hit driver, you must hit the fairway.

2. Wedge = Green – Any wedge must finish on the green.

3. Avoid the Dead Zone (30–80 yds) – Play to full yardages or inside 30.

4. 15-Yard Safety Rule – Required carry + 15 yards = minimum capability.

Example: A 200-yard carry demands a reliable 215-yard average carry. No “max” swings allowed. If your stock carry doesn’t meet the number, you must lay up.

Know Your Numbers

Carry distances must reflect repeatable shots, not perfect strikes. Outliers are removed. The stock number — hit 7–8 times out of 10 — becomes the decision baseline. These numbers are written into the yardage book as a visual contract.

Conclusion

Jentsch replaced guesswork with measurement. Ball flight became the only objective truth in a subjective game. His methods anticipated the data era and remain foundational in modern biomechanics, launch monitor coaching and AI-driven analysis.

Golf, in his system, is no longer about hope — it is about physics, discipline and measurable reality.
