7a0 Data & Editorial Methodology

What the archive includes

7a0 is a selective playable archive rather than a complete encyclopedia of every World Cup participant. The build process synchronizes the national-team and tournament-squad index used by the game, then calculates the current number of represented teams, editions, squads, player profiles and squad records from those files.

The World Cup teams database and the tournament-year directory distinguish the size of the historical competition from the number of squads currently playable in 7a0. A missing standalone guide does not mean a team is absent from football history.

How historical facts are checked

Tournament hosts, champions, final scores, field sizes and major results are checked against official tournament records and match reports wherever available. Country, tournament and squad guides use those facts as a base, then add original explanations of eras, roles, tactical context and how the material connects to the game.

For example, the 2026 directory was updated after FIFA published the completed tournament standings and Spain's 1–0 extra-time victory over Argentina. See the official FIFA 2026 final standings.

When reliable references conflict, the page should describe the uncertainty or avoid presenting the disputed detail as settled. Historical text may be revised when stronger evidence becomes available.

Playable squad data and ratings

The game data stores tournament-specific squad entries with player names, shirt numbers, eligible positions, ratings and legend markers. A player may appear in more than one tournament squad, so the number of squad records is larger than the number of unique player profiles.

Ratings, eligible positions, legend labels, tactical benchmarks and simulation values are editorial game decisions. They are not official FIFA ratings, objective historical rankings or predictions of real matches. Values can change after data review, balance testing or a well-supported correction.

How 7a0 ratings differ from official records

A 7a0 rating belongs to one tournament squad, not to a player's whole career. The same person can have different values in different World Cups because the game stores shirt number, eligible positions and rating on that year's squad entry.

The Coach's Report and the simulator use the same attack and defence totals. Those totals weight positions differently: strikers and wingers contribute most of the attack value, central midfielders sit in the middle, and goalkeepers contribute almost none of the attack score. Defence is weighted in the opposite direction. A high-rated striker therefore does not automatically make a weak back line look strong.

Positions are legal constraints, not labels. A centre-back cannot occupy every defensive slot, and a striker is not treated as a winger because the rating is high. That rule is original to the game and is why a famous name can be a poor pick for the open position.

Tournament simulation benchmarks

The simulator compares the finished XI against fixed internal opponent levels rather than against live betting odds or official FIFA rankings. The current campaign uses these power benchmarks: group matches at 68, 72 and 76; round of 16 at 79; quarter-final at 83; semi-final at 87; final at 91.

A result is produced from the lineup, playing style, those benchmarks and a generated seed. Replaying the same XI with a new seed tests variance on a different path. Replacing the lowest-rated pick while keeping the opponent path tests whether one change actually moved the record. Neither mode claims that one historical generation was objectively better than another.

Why only some entries have standalone guides

A database row is not automatically turned into an indexable article. A standalone country, tournament or squad guide is published only when it has enough original context to answer a distinct user question instead of merely repeating a name, year and player list.

• Country guides compare meaningful generations, championship history, archive coverage and cross-era lineup choices.
• Tournament guides explain the field, groups or stages, decisive teams, players, results and the relationship between historical participants and playable squads.
• Squad guides include campaign results, a verified historical lineup where available, tactical identity, contributor roles, complete playable data and related historical pages.
• Thin placeholders, automatically generated doorway pages and pages with no added editorial value are not intentionally submitted for indexing.

Updates, corrections and review dates

Build-time synchronization updates the playable data files and recalculates archive statistics. Editorial pages are reviewed separately because a data refresh can change a squad identifier or archive count without changing the historical explanation on the page.

To report a squad, player, result or wording issue, email support@7a0.online with the page URL, the proposed correction and a reliable supporting source. Reports are reviewed before the public content or game data is changed.

Independence and attribution

7a0 is an independent, unofficial football game. References to tournaments, teams and players identify historical subjects and do not imply endorsement by FIFA, national associations, clubs or represented players.

External sources support factual verification; their articles, photographs and databases are not republished as 7a0 content. Editorial summaries and the game system are created for this website.
