The Six Attributes
What Braking, Speed, Pace, Racecraft, Control, Experience and the Overall measure, why each one matters and how Braking Lab computes it.
Your card has six attributes and an Overall. Each one is a score from 0 to 100 on a scale that is the same for every driver and every car: an 80 in Braking is an 80 for any driver, in any car.
How a Score Is Built
- Each session gives a value for the attributes it can measure.
- A score is the median of those values, weighted by age: recent sessions count more. One odd session cannot move it.
- Time alone does not move a score. A score changes when new sessions come in, or when a session leaves your profile.
- Most attributes measure how repeatable you are, not how fast you are. Speed is the attribute that reads where you start.
Overall
What it is. Your overall level, summed up in one number from 0 to 100.
Why it matters. It gives your level at a glance, on the same scale for everyone.
How. It comes from your scored attributes. Some weigh more than others: Braking and Speed the most, Experience the least. An attribute with no data does not pull you down: the others cover its share.
Braking
What it measures. How much your braking point moves from one lap to the next.
Why it matters. If your braking point moves, every corner starts differently, and you can’t fine-tune a line or a setup.
How. In each braking zone, the moment you hit the brake, lap after lap, and how far it strays from your usual point. Practice and qualifying weigh more than races, where traffic moves your braking.
Speed
What it measures. Where you usually qualify within your class.
Why it matters. Starting near the front keeps you out of first-lap traffic. And since iRacing splits races by iRating, your spot is measured against drivers of your level.
How. The share of your class grid that starts behind you. Races against people with a qualifying grid count, in a class of 8 cars or more.
Pace
What it measures. How consistent your laps are: how much your lap times vary from each other. It doesn’t measure how fast you are.
Why it matters. One fast lap isn’t enough: in a race, the driver who repeats their pace lap after lap wins.
How. How much your lap times vary. Laps far slower than your best, like traffic laps or a mistake, don’t count. Practice and qualifying weigh more than races.
Racecraft
What it measures. How you race: incidents and places gained or lost.
Why it matters. A race is won among cars: passing without contact and defending without going off.
How. Incidents per 10 race laps and, when Capture records the spots, the places gained or lost. Only races against people count.
Control
What it measures. The share of your qualifying and race laps that are clean.
Why it matters. A dirty lap costs positions and Safety Rating, and undoes the work of the others.
How. Clean laps over all your qualifying and race laps, pit laps aside. Practice doesn’t count: going off there is part of finding the limit. Control reads iRacing’s clean-lap flag, so it is iRacing only.
Experience
What it measures. The races against people among your 500 most recent sessions.
Why it matters. Every start teaches what practice can’t: the first corner, the traffic, the pressure.
How. It counts your races against people. Races against the AI do not count. Experience is never your “Where to improve”: you cannot train it, you can only race.
When an Attribute Has No Score
An attribute shows the reason instead of a number:
- No data yet. No session has measured it.
- Needs 3 sessions with data. You have fewer than 3 sessions that measured it.
- None of your sessions counts for this attribute yet. For example, Control with practice sessions only.
A missing attribute is never a zero, and it does not lower your Overall.
