Archive transparency
An independent database.
Always moving.
The portal queries its own PostgreSQL database. Sources feed an import, validation and reconciliation pipeline; no search depends on an external API responding at that moment.
Scheduled sources completed their checks and the database is available for research.

From source to research
How updates work
Automated, reversible and checked before any data reaches the public.
- 01Collection
The current season is checked four times a day; the historical archive, daily.
- 02Reconciliation
Names, identifiers, players, tournaments and dates are matched to existing records.
- 03Validation
Duplicates, invalid matches, future dates and matchup integrity are checked.
- 04Publication
Only a complete import replaces the previous state; after a failure, the valid database remains active.
Ranking trajectories
What a documented week means
A measure of this archive's evidence, not a claim of official continuous weeks.
One calendar week
Top 10, 20, 50 and 100 permanence counts each calendar week with at least one archived snapshot placing the player inside that range. If the archive has more than one list in the same week, it still counts once.
No interpolation
The archive is mostly weekly, but its cadence and depth vary by era and source. Weeks without a snapshot are not filled, even when the player appears immediately before and after a gap.
Canonical identity
Strong source identifiers and carefully reviewed name evidence can join historical and current records for the same player. Ambiguous identities remain separate; raw ranking entries are preserved.
Peak and progression
The peak date is the first archived snapshot at the player's best position. The chart keeps the latest recorded ranking in each month for readability, while permanence is calculated from every available snapshot.
