Clean Historical Context
Every draw in every game we cover, put on the same clean footing before we compare anything. That is what makes the rest honest.

The one-sentence definition
Clean historical context means every draw in every game is put on the same footing before we compare anything.
Why it matters to you
When you look at how often a number has appeared, you want to trust the number you're seeing. That only works if the raw data — collected from lots of different sources, over many years — has been cleaned up first.
Same date format. Same time-zone rules. Same handling of special games like Fireball or Double Play. Same treatment of the day the game’s rules changed.
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 does it
We fix all of that in one place, so everything downstream — every report, every Oracle answer — reads from the same clean version. When you see a number on Stepzero, it came off the same version of the history everything else did.
- One canonical draw record per game, per session, per date.
- Era boundaries applied on the date rules changed.
- Add-ons and special sessions tracked separately, never blended into the base draw.
The honest limit
Clean data is not a prediction. It's the floor everything else stands on.
