Safety Rating Methodology
Safety Rating Methodology Beta
How the Rush SR safety board turns clean running and incident rulings into one transparent number.
Safety Rating is in beta for 2026. The formula, the session weights, the incident matrix, and the advisory bands are all expected to change during the season as we see how the numbers behave over a full calendar. Ratings are recomputed from the incident log every time, so a tuning change moves every driver’s number at once, including past weekends. Treat a rating as the current reading of a system still being calibrated, not a settled result.
What it measures
Safety Rating measures conduct in the Rush SR field. It does not reward pace, finishing position, or championship points.
The rating is recomputed from the published incident log. It is never entered by hand and never stored as a separate driver field. Each eligible weekend contributes green-flag exposure and the incident points attached to steward rulings. Clean running lifts the rating gradually; incidents reduce it.
Test days are not counted. The current intake includes only official days under the Rush National Series sanctioning bodies, currently the GridLife rounds; practice and warmup sessions carry 0.25 weight, while qualifying and race sessions carry 1.00.
The same replay is used on driver profiles, the public board, and the steward tools. This page displays the live values currently used by the replay.

Each driver opens at 2.00, so the bands below that line hold drivers whose incidents have outweighed their green-flag running so far, and the bands above hold drivers who have run more clean minutes than they have given back. A driver with one weekend sits close to 2.00 either way: the rating moves slowly until there is enough running behind it to move.
The live rules
The table and formula below are rendered from the live raw_sr_rating_settings option and the deployed Safety Rating matrix.
The live formula
New rating = 5.00 − (5.00 − previous rating) × e−0.5 × E ÷ 500 − (P ÷ 12)
- E is green-flag exposure, weighted by session type.
- P is incident points, weighted by session type. A flagged full-course-yellow incident multiplies shared and at-fault points by 2; not-at-fault grades are exempt.
- 500 is the fixed season anchor. It is a tuning constant, not a measurement.
Session weights
| Session | Live weight |
|---|---|
| Race | 1 |
| Qualifying | 1 |
| Practice | 0.25 |
Damage/DNF grades that are shared or at fault, and reckless grades, score at full session weight. This prevents serious outcomes from becoming cheaper in practice.
Live incident points
| Incident | Not at fault | Shared | At fault |
|---|---|---|---|
| Solo off, spin, or 4-off | — | — | 2 |
| Rule infraction (PUY, jump start, blend line) | — | — | 4 |
| Mechanical failure | — | — | 1 |
| Contact or squeeze, no consequence | 1 | 2 | 4 |
| Costing a position, a spin, or an off | 1 | 3 | 6 |
| Causing damage or a DNF | 2 | 5 | 10 |
| Reckless or wholly avoidable | — | — | 40 |
The row is the worst consequence caused by the incident. Mechanical failures are the lowest chargeable row, solo offs are next, and damage/DNF uses the live matrix above. An infraction escalates to the consequence row when it caused contact or impeded safety trucks.
Advisory status
Driver under review is an advisory recommendation based on the full-precision rating and appeal state. The sanctioning body retains final discretion over entry and sanctions.
Ratings are cumulative and do not decay. Appeals keep affected weekends provisional until their review windows close.
What-if simulator
Build a season one weekend at a time. Each box is a whole weekend: practice, qualifying, and race combined using the live session weights. This is a read-only projection using the live matrix and formula above.
New drivers start at 2.00. Published drivers use their current live rating.
Weekend 1
Per-session minutes; this weekend aggregates practice + qualifying + race.
Add up to 24 weekends. Delete a weekend with the x in its top-right corner; at least one box remains.
Projected final rating
Starting at 2.00, 1 weekend projects 2.32 (+0.32).
Season trajectory
- Weekend 1: 2.32 (+0.32)
The simulator never saves a rating or incident. Display values are rounded to two decimals; calculations keep full precision.
How incidents are graded
Each involved driver receives a separate grade. The row records the worst consequence caused by the incident, not simply what happened to that driver’s own car. The column records the steward’s responsibility ruling: not at fault, shared, or at fault.
A solo off, a rule infraction, a mechanical failure, contact, a lost position, damage or a DNF, and reckless conduct are distinct rows. A mechanical failure is not treated as driver fault unless the steward assigns that row and responsibility. A rule infraction escalates to the consequence row when it caused contact or impeded safety workers.
Damage and reckless outcomes are not discounted by session type when the grade is shared or at fault. Serious consequences should not be cheaper because they happened during practice.
Full-course yellow escalation
A steward can mark the incident that caused a full-course yellow. The live multiplier applies only to shared and at-fault grades. Drivers who were not at fault are not escalated for being collected in someone else’s caution-causing incident.
Exposure counts green-flag minutes. Formation, pace, out-lap, in-lap, double-yellow, and red-flag time do not count as green running.
Advisory status
“Driver under review” is an advisory recommendation, not an automatic suspension. The rating uses full-precision values and settled appeal state to determine its recommendation band. The sanctioning body retains final discretion over entry and sanctions.
Ratings are cumulative and do not decay. Appeals keep affected weekends provisional until the applicable review windows close.
