Ranking Rule
Rank #1 is the best outcome for a factor. Rank points equal the comparison group size minus rank plus one, then the user's priority weight is applied.
Data
Data Sources
DecisionVision is built around transparent comparison. The core product rule is that every live calculator should have 16 intuitive factors and every compared subject should be ranked in every factor.
Source-Backed Boards
Live boards use public datasets, official records, product specifications, or published reference sources. Boards that do not meet the current source standard are kept out of the visible directory until they are rebuilt.
Scoped Universes
Some calculators intentionally compare a certified subset instead of every possible option. For example, the live laptop, U.S. airline, full-service restaurant, streaming, mortgage, military branch, and tennis split boards are scoped to candidates with complete source-backed rows.
Derived Scores
Some factors are normalized or derived from other visible factors, such as value blends or balance scores. Derived factors should be read as decision-support signals, not separate outside measurements.
Estimates And Rebuilds
Controlled-estimate or best-effort boards are not promoted as live product pages unless the page clearly discloses the method and passes the source-review gate. Current weak boards are tracked as rebuild candidates instead of being quietly promoted.
Images
Images may come from approved local assets, generated visual fallbacks, Wikimedia-style public references, or source-linked web images. If you own rights to an image and want it removed or credited differently, contact us.
