Product Comparison Methodology

Evidence status: Methodology published; named product results and rankings withheld.

Before a comparison

Define the reader job, inclusion criteria, exact product versions, sample source, conflicts, claimed features and failure conditions before testing begins.

During a comparison

Record setup, dimensions, surfaces, direction, environment, repeats, exclusions, defects and adverse observations. Keep manufacturer claims separate from measured observations.

Before publication

Verify that the tested sample matches the named product, retain the evidence record, state limitations and avoid converting a narrow observation into a universal performance or safety claim.

Retest and correction

Material design changes, credible corrections or inconsistent results can trigger a retest or withdrawal. Until this process occurs, GolfGNG does not publish named rankings or claim firsthand testing.
