What the coach can do

The coach compares your driving with the target lap you are chasing, corner by corner, and talks to you about the differences that cost you time.

The structure of a corner

The coach reads every corner in four phases, the same way a human coach would walk it:

• Entry. The braking zone and turn-in: where you brake, how hard, and the speed you carry toward the apex.
• Rotation. Getting the car turned: trading brake (trail braking) for steering until the nose points at the exit.
• Transition. The handover from turning to accelerating: how early and how smoothly you get back to the throttle.
• Exit. The drive away: feeding in full power and the speed you carry onto the next straight.

In the review screen, Entry is called Setup and Exit is called Launch.

A mistake in one phase spills into the next: brake too late and the rotation suffers; rotate too little and the exit pays for it all the way down the following straight. The coach looks for the cause of a loss, which is often a phase before the one where the time went.

Different types of feedback

• A correction after the corner. What went wrong and what to do instead, while the corner is still fresh.
• A reminder on the way in. Once it has told you something, it reminds you before the corner on the next lap, in time to act on it.
• Recognition when you fix it. Apply the change and it tells you, and says how much quicker the corner got.
• Progress across laps. It remembers what it said and follows the same problem lap after lap, detecting improvement, regression and consistent mistakes.

Coaching focus

The coach focuses on the corners costing you the most time and prioritises those. Every new lap, it learns from your performance and updates its focus. It counts the time lost in each phase of a corner, and the time that corner costs you on the straight or corner after it.

The Coaching Sensitivity setting decides how small a loss is still worth mentioning: see Coaching sensitivity.

Coach attention

The coach analyses your actions in real time and always picks the best available moment to speak.

• It does not talk over your hands. For instance, if it knows you’ll be hard on the brakes soon, it prefers to wait.
• When more than one thing needs saying about a corner, related problems arrive as one message.
• It skips a corner where you went off, spun or lost an abnormal amount of time. A crash tells it about the crash rather than your technique, so it neither corrects nor praises that corner.

If it says less than you expected, that is usually deliberate. See The coach is not talking.
