This chart tells you "how much of your tire's grip you actually used".
Principle (10 sec)
Total tire grip is fixed. You ask it to do 3 things:
accelerate (throttle) / decelerate (brake) / turn. Do several at once, each gets less.
The usable limit drawn out is a circle — that's the "friction circle".
Good driving = always at the circle's edge (using all grip); conservative = clustered near center (wasted).
How to read (axes and forces)
• X axis = cornering G. Right = right corner, Left = left corner.
• Y axis = decel/accel G. Up = braking, Down = accelerating.
• Each dot = an instant on your best lap, color matches which corner (T1-T12, gray = straight).
• Red dashed circle = your session's grip limit.
• Gray thin dashes = 0.5g / 1g / 1.5g reference circles.
What problems can you spot (4 signal types)
How to improve (specific actions)
1. Main gap = bottom (insufficient trail brake): see "weak corners" at top. At these corners you brake-then-turn.
Try: in the last 0.5-1s before entry, keep light brake while starting to turn (release brake a beat later than steer-in).
This shifts weight to front tires, increases grip, allows higher entry speed.
2. Main gap = accel phase: hesitation between brake-release and full throttle on exit. Try: on exit go straight to full throttle, let car find its own limit.
3. Main gap = one side's corners: in that direction, push harder, steer to limit, see if car understeers (understeer = true limit).
Note: G values inferred from GPS speed + heading (no IMU). After 0.2s smoothing + extreme clipping, karting scenario error ±5%. Only A-type braking corners count for trail brake evaluation; K-type high-speed kinks don't brake and don't count.
Opening
Your best lap was L6 at 69.16s, but the theoretical 3-sector best lap could be 68.6s, giving you a recoverable 0.56s. S1 was quite stable, but there's room for improvement in S2 and S3.
Style sketch
You're an aggressive late-braker with a steady rhythm. You tend to apply throttle early on exit, but your line consistency could use some work.
Top corners to improve
- T3: This is a left sweeper with a radius of 54.4m and a grip ceiling of 91.1 km/h, though your kart tops out at 86.2 km/h. Your best apex was 83.2 km/h in L4, while your worst was 66.0 km/h in L1. There's a 2.7 km/h gap to the achievable apex, worth about 0.122s per lap. The issue is that you're braking too early and not carrying enough speed through the corner. Next session, brake 3m later, aim for an entry speed of 85 km/h, and push the apex to 86 km/h.
- T5: A right sweeper with a 52.4m radius and a grip ceiling of 89.4 km/h, capped by your kart's 86.2 km/h. Your best apex in L5 was 83.6 km/h, and your worst in L1 was 70.0 km/h. There's a 2.6 km/h gap to the achievable apex, worth around 0.109s per lap. You're braking too early and not getting back on the throttle quickly enough. Next time, brake 5m later, target an entry speed of 85 km/h, and get back on the throttle 10m earlier.
- T19: A left turn with a 25.1m radius and a grip ceiling of 61.8 km/h. However, it's linked to T18, and your achievable apex is 50.7 km/h. Your best apex in L6 was 49.8 km/h, and your worst in L2 was 45.5 km/h. The real improvement lies in T18. Exit T18 earlier on the gas to increase T19's entry speed.
Consistency observation
You showed good consistency in some corners, but T3 and T5 had significant time gaps between your best and worst laps. In T3, your best lap was 2.12s, and your worst was 2.6s, a 0.48s gap. In T5, the gap was 0.28s. The key is to replicate your best lap's braking, entry, and exit on every lap.
Trail braking observation
Your trail brake ratio session-wide is 81%, but T14 is only 37.5% — you finish braking before turning in. Try releasing the brake one beat later than the wheel, let it carry into the apex. You could save around 0.1 - 0.3s per lap there.
Rhythm observation
Your rhythm was decisive this session; no real hesitation.
Safety note
On L7, I saw your speed drop from 84.4 km/h to 0 km/h mid-lap — that looks like a mid-lap stop. Hope you're okay. What happened — contact, off-track, or yielding for someone? That matters more than lap time.
Closing
You've shown great potential this session. Your best lap in T3 was very close to the achievable apex. Next session, focus on T3. Brake later and carry more speed through the corner to get closer to the ceiling.
