How Dirt Ranks Works
Dirt Ranks compares what a driver did, who they did it against, and how strong the race was. The exact weighting stays private, but the basic process looks like this.
Dirt Rating
A Dirt Rating moves based on a driver's performance compared with the competition and the strength of the event.

Race Rating
Race Rating describes the strength of the race itself, not how well one specific driver performed.
Definitions
Dirt Rating
A driver's overall Dirt Ranks performance rating. It changes as new ranked races are completed.
Feature Result
Where the driver finishes in the main event. The result is evaluated in the context of the drivers they raced against.
Competition
The strength of the drivers a competitor races against, including who they finish ahead of and behind.
Field Quality
How strong the drivers in the race are based on their Dirt Ratings.
Field Depth
How far that quality extends through the field. A race with strength throughout the lineup rates differently than one with only a few highly rated drivers.
Race Rating
A score representing the overall strength of an event's field. It provides context for each driver's result.
Rating Change
The movement applied to a driver's Dirt Rating after a ranked race. Stronger-than-expected performance generally helps; weaker performance can lower it.
Dirt Rating vs. Points
Dirt Rating is separate from track, series, or sanctioning-body championship points. Points follow that organization's rulebook. Dirt Rating is designed to compare performance across ranked races.
The exact formula, weighting, adjustments, and safeguards used by Dirt Ranks are intentionally not published.
