The governing rule
Methodology
Accuracy before completeness.
A smaller verified answer is more useful than a larger answer built from assumptions.
That applies at the setting level. A charted loft change can sit beside a null lie value when that is what the documentation supports.
Every model references an adapter. Every setting references an official source. Measured changes are labeled separately from expected fitting effects.

Recommendation pipeline
How a starting point is ranked
Resolve the club
The model maps to one documented adapter.
Load the chart
Handedness switches the full matrix where required.
Score settings
Verified positions are compared with miss, trajectory, and current setting.
Explain tradeoffs
The best two options show measurements, expectations, and conflicts.
Official measured change
What the chart states
- Loft delta
- Lie delta or designation
- Face angle when published
- Setting and handedness
Expected fitting effect
What may happen
- Higher or lower launch tendency
- Draw-side or fade-side start tendency
- Face-presentation implications
- Variables to validate by testing
Known limits
What the optimizer does not know
It cannot see face-to-path, strike, dynamic loft, speed, shaft delivery, or how a golfer reacts to the look at address.
Every recommendation is a controlled starting point—not a diagnosis and never a promise to fix a slice or hook.
