Evidence ladder

Every source receipt in a Golf Buyers Lab guide carries one of five evidence states. The ladder moves from third-party verifiable facts up through sustained-use experience.

  1. Official source — a claim from a manufacturer product page, manual, support document, pricing page, software vendor, or rules body. The guide links to the source.
  2. Source-led analysis — our judgment about buyer fit, total cost, constraints, or tradeoffs grounded in official-source facts. Always labeled as analysis.
  3. Community report — a claim supported by a relevant third-party test, dataset, or documented community measurement. The guide identifies and links the evidence.
  4. Hands-on test — an observation from documented use. The notes must identify the product, date, firmware or software version, setup, conditions, and comparator where relevant. A hands-on-test label requires a non-null receipt ID derived from those notes. Without that receipt, the evidence stays at a lower tier.
  5. Long-term use — sustained use across multiple sessions, firmware updates, or conditions over an extended period. Like hands-on test, a long-term-use label requires a non-null receipt ID. A one-time test does not qualify.

Source-led review process

  1. Define the buyer question and the constraint that actually changes the answer: budget, room depth, device support, subscription tolerance, portability, or required metrics.
  2. Check current official prices, product status, manuals, setup requirements, compatibility, and recurring costs.
  3. Record a checked date and link material claims to their primary sources.
  4. Separate measured metrics from calculated or estimated outputs when the vendor documents that distinction.
  5. State who should buy, who should skip, and what new fact would change the recommendation.

What we evaluate

The recurring mechanisms are accuracy claims, measured versus calculated data, setup friction, room requirements, subscription costs, required balls or accessories, platform compatibility, portability, data export, warranty, and support limits.

Freshness and corrections

Prices, subscriptions, firmware, and availability move. Material updates receive a new checked date. If a source disappears or a claim can no longer be verified, the claim is removed, qualified, or held from publication. See the editorial policy for our correction and update log.
