Clean Historical Context
Clean historical context means every draw in every game is put on the same footing before we compare anything.
Clean historical context — every draw put on the same footing before any comparison.

Glossary term
Before we compare anything, we put every draw on the same footing. That's what makes the rest honest.
Why It Matters
Without this step, a comparison can quietly lie to you. A "hot" streak might just be a source that started reporting a game earlier. A "drought" might just be missing data.
How Stepzero Uses It
We fix the raw data in one place — same date format, same time-zone rules, same handling of add-ons and rule changes — so every report and every Oracle answer reads from the same clean version.
Example
Florida Pick 3 records from the 1990s use a different format than today. Stepzero puts them on the same footing so a drought or frequency count spans the whole history honestly.
