Factors

Every one is long term: this list publishes no short-timeframe set, because excluding a source list's long-term compartments is that list's convention and not this one's. Follow a category for the factors under it.

The headline is the agreement: across every method characterised, the 3 implementations that state a row agree exactly — same float, full precision — on 36,242 of the 36,948 rows more than one of them states. A difference is not an error; most are modelling choices between competent teams.

The whole report Coverage across contexts

Things characterise did not silently resolve. None of them is a factor this list changed: where two numbers cannot both be published, neither is.

Factor collisions 5 Two source rows reach one consensus flow and state different numbers for one category, in one place. Neither is published: the disagreement is evidence about the matching, and averaging it would hide that. Unit crossings 3 A factor stated per kilogram, published against a flow measured in megajoules. The number is converted by the flow's own property, and the crossing is recorded rather than assumed harmless. Declined numbers 232 The build settled two rows that turned out to be one flow, and this is the number it did not keep (#375). A reader comparing implementations has to know the number they are comparing was chosen from two. Flows not reached 231 A source row this list has no flow for, so its factor has nowhere to land. A question for the merge rather than for this layer. Numbers carried onto a survivor 16 An identifier this build retired held a factor the flow that replaced it states nothing for, so the number was carried onto the survivor (#778). The one case where following a redirect adds a factor rather than restating one. Redirects not followed 15 An identifier this build retired carries factors, and its redirect is one a consumer is told to refuse — two source contexts our vocabulary cannot tell apart. The numbers are reported here rather than republished on the survivor (#778).
