How it works

Rules & ratings

Two numbers follow you across every SRC series: a skill rating and a safety rating. Here is exactly how they move.

SRC Rating — skill

Each session is scored as one multiplayer match: every classified driver is compared against every other, expected results from current ratings versus the actual finishing order.

E(i vs j) = 1 / (1 + 10^((Rj - Ri) / 400))
ΔRi       = K · Σ (Sij - Eij) / (N - 1)      Sij = 1 if i beat j, else 0
K         = 32 · tier · placement · field_strength

Everyone starts at 1500.
Event tier: daily 0.6 · league round 1.0 · finale 1.3.
First 5 races are provisional — the number is greyed and off the leaderboard.
A DNF from your own mistake counts as last; being wrecked or a server crash voids the change.

Safety Rating

An incident rate per corner attempted, smoothed over your recent sessions and mapped to a letter band from S down to F.

corners_attempted = laps · corners_on_track
CPI  = corners_attempted / max(incident_points, 0.5)
SR   = corner-weighted rolling average of CPI  ->  band

Incident	Points
Track-limits warning	0.5
Spin, no contact	1
Pit-lane speeding	1
Light contact	2
Causing a collision	4
Ramming / DSQ offence	8

Incidents come from ACC penalties in the result file, live accident events from the broadcast stream, and steward rulings — all in one place. Thresholds are calibrated on real SRC data each season.
