Public methodology

Official-Spec Capability Model

Version 1.0.0 turns sourced manufacturer specifications into an inspectable comparison. It is a decision aid, not a laboratory rating or a claim of objective product quality.

Visible inputs

Every scored input, cap and category weight is shown.

Unknown stays unknown

Missing evidence never becomes zero, false or an implied failure.

Fail closed

A weighted category without comparable data cannot produce a winner.

Normalization

Category formulas

Display

Medium

40% published peak brightness (capped at 3,000 nits) + 35% pixel density (scaled from 300–500 ppi) + 25% maximum adaptive refresh rate (capped at 120Hz).

Peak-brightness figures can use different manufacturer test windows and are not treated as independent measurements.

Camera capability

Medium

25% native telephoto reach (capped at 5x) + 15% optical-quality reach (capped at 10x) + 35% published pro workflows (four-item ceiling: Log, RAW, external recording and genlock) + 5% 8K availability + 20% native rear-camera count (capped at four).

This measures published hardware and workflow coverage. Frame-rate modes are excluded because manufacturers classify normal and slow-motion capture differently. It does not claim to measure photo or video quality.

Battery claims

Low cross-brand

65% claimed local-video duration (capped at 35 hours) + 35% claimed charge percentage per minute (capped at 2.5).

Both inputs are manufacturer up-to claims. Different test protocols make the resulting cross-brand score provisional.

Performance

Unavailable

No score until comparable CPU, GPU and sustained-load results exist under a shared independent protocol.

Chip names and generation-over-generation marketing percentages are deliberately insufficient.

Longevity

Evidence-dependent

Published model-specific software-support duration, normalized against a seven-year ceiling.

A brand’s historical behaviour is not converted into a guarantee. Missing fixed commitments remain unknown.

Personal match

Weighted mean

match = Σ(priority × category score) ÷ Σ(priority)

Priorities range from Ignore (0) to Critical (3). Deal-breakers are evaluated separately and never secretly subtract points.

Price model

Value equivalence

equivalent price(B) = price(A) × score(B) ÷ score(A)

This is score-per-pound equivalence, not a declaration that a product is rational for every buyer. MSRP is labelled as a reference price and never disguised as a live offer.
