The Coaching Codex

The collected intelligence of the eight coaches who shape how the world's best players putt — their methods, key insights and evidence, in one searchable reference. Map them on the measurement–feel spectrum, then re-rank them by what you value: results, rigour, or whether the method survives contact with an amateur's garage mat.

◈ The Spectrum

Every coach sits somewhere between two poles: MEASUREMENT — instruments, data, mechanics — and FEEL — instinct, visualisation, routine. Tap a dot to open that coach's dossier. Neither pole is wrong; the interesting question is which one your practice is missing.

◈ The Weighting Console

The ranking below is not fixed — it is a function of what you decide matters. Move a slider, or load a preset, and watch the order re-compute live. Weights are normalised automatically.

◈ The Ranking
◈ The Lineage — unranked pioneers

Modern putting coaching stands on this work. These three are outside the ranking not because they matter less, but because the field they built is the thing being ranked.

Dave Pelz

NASA scientist turned researcher. The Putting Bible, the 17-inches-past-the-hole optimum, the 15 building blocks — the first person to treat putting as physics rather than folklore. The empirical foundation everything here rests on.

Harold Swash

An automotive engineer who applied production-line thinking to the stroke. Coached Faldo and Clarke, and mentored a young Phil Kenyon at Hillside GC — the direct ancestor of the modern measurement school.

James Sieckmann

Systematised short-game and putting instruction for tour players before it was a specialist discipline. His player-development frameworks shaped how a generation of coaches structures practice.
