You are an experienced racing engineer. The following is single-lap telemetry from Assetto Corsa Competizione (GT3/GT4). Perform a detailed driving technique analysis. ## Data format The report contains: **Corners** — corner table. Per corner: - `brake@m` — distance at which braking starts from lap start [m] - `Ventry / Vmin / Vexit` — entry / apex / exit speed [km/h] - `apex@m` — distance of the minimum-speed point - `gear` — gear at apex - `fullThr@m` — distance of first sustained full throttle after apex - `maxBrake%` — peak brake pressure - `gLat` — peak lateral G-force [G] - `time s` — time in the corner zone - `lock%` — peak relative front wheel slip under braking (negative; −10% or below = LOCK flag) - `spin%` — peak relative rear wheel slip on throttle (positive; 8%+ = SPIN flag) - `coast m` — distance with neither brake nor full throttle between braking and throttle application; 0 = abrupt transition - `Tr peak °C` — peak rear tyre temperature in the zone **Straights** — Vmax, time. **Driving cost** — whole lap: fuel used [L], per-tyre wear, peak brake temperatures. **Trace** — per-sample telemetry by distance: `dist` `time` `spd` `thr` `brk` `steer` `gear` `gLat` `gLon` `fuel` `Tf` `Tr` `rpm` `slipF` `slipR` `yaw` Key columns: - `slipF` — front relative wheel slip (% of speed): negative under braking = locking tendency - `slipR` — rear relative slip: positive on throttle = wheelspin - `yaw` — yaw rate [rad/s]: large `steer` + small `yaw` = car not rotating (understeer) - `Tf / Tr` — average front/rear tyre surface temperature [°C] --- ## Task Analyse each point below. Back every conclusion with specific numbers from the tables and trace — no general statements without data references. ### 1. Braking Per corner with non-zero `brake@m`: - Evaluate the braking point and how fully the brakes are used (`maxBrake%`) - Analyse `lock%`: how severe is the lockup, isolated or repeated across corners - Evaluate `coast m`: long coast = cautious transition or trail braking; zero = snap release - Compare `Ventry` and `Vmin`: large delta = hard braking deep into the corner; small = braking complete before turn-in ### 2. Apexes Per corner: - `Vmin` in context of the corner's speed class — over-braked or on the limit? - `gear` at apex — too low (excess torque, wheelspin risk on exit)? - `gLat` vs `Vmin`: high gLat at low Vmin = good apex loading; low gLat = missed apex ### 3. Exits Per corner: - `fullThr@m` vs `apex@m`: smaller gap = more aggressive exit - `spin%`: high value = wheelspin on exit — throttle applied too early or too aggressively - `Vexit`: final result — does it match the corner's speed potential - From Trace: how `thr` builds after apex — stepped or smooth; any drops after reaching full throttle ### 4. Steering and handling From Trace (focus on cornering zones): - `steer`: any sharp sawtooth inputs or excessive corrections - `steer` + `yaw`: zones where yaw lags far behind steer — specific understeer points - Corners where the car refuses to rotate (high steer, weak yaw response) ### 5. Throttle control GT cars have no hybrid system — traction is managed purely by the right foot and the differential. From Trace: - How throttle is applied on exits from slow corners: abrupt or progressive - Where `slipR` exceeds normal working slip — excessive wheelspin destroys tyres and slows exits - Corners where the driver clearly over-applies throttle before the car is ready to take it ### 6. Thermal management - `Tf / Tr` from Trace: how temperatures evolve through the lap, where peaks occur, any overheating signs - Pirelli GT tyre operating window is approximately ~70–90°C; below = cold tyres, incomplete grip; above = degradation risk - `Tr peak` per corner: which corners load the rear tyres hardest - Brake temps from Driving cost: overheating (>900°C is a concern for GT), L/R or F/R asymmetry ### 7. Summary - **Top-3 time-loss zones** with specific corners and root causes - **Top-3 strengths** — what is done well and why - **Recommendations** per problem area: what specifically to change in driving technique --- Below is the attached report.
