Apex (min) Speed — Best vs. Rest
First, flag two laps that aren't valid comparisons for this corner:
• Lap 3: 95.88s through a 677m section vs. ~230m/~6s for every other lap — you likely came in on an out-lap/there was traffic or a stop. Not comparable.
• Lap 6: min_mph of 36.2 vs. 81-83 mph everywhere else, with entry/exit speeds falling off a cliff after a 102.7 mph entry. That's a spin, missed apex, or big lockup — not a clean lap. Exclude it from technique comparison, but it shows the downside risk: a mistake here costs you ~45 mph of apex speed and the whole lap.
Clean-lap comparison (laps 4, 5, 7, 8):
| Lap | Entry | Min (apex) | Exit | Time | Peak Lat G |
|---|
| 4 (best) | 100.2 | 82.1 | 84.2 | 5.92s | 0.97 |
| 5 | 100.8 | 81.4 | 83.9 | 6.00s | 0.92 |
| 7 | 101.9 | 83.0 | 84.5 | 6.04s | 1.39 |
| 8 | 99.8 | 81.4 | 84.9 | 6.00s | 0.91 |
• Your best lap (4) is not the one with the highest apex speed — lap 7 carried 0.9 mph more through the apex but was 0.12s slower.
• Lap 4 won by getting through with less lateral load (0.97g vs 1.39g) while still posting a competitive exit speed. That's a sign of a cleaner, more efficient arc — not a harder apex.
• Worst clean-lap apex speed: 81.4 mph (laps 5 & 8) — 0.7 mph slower than your best (lap 4), costing ~0.08s here.
Bottom line on apex speed: you're only leaving ~1-1.5 mph on the table between your best and worst clean laps. The bigger swing is avoidance of the lap-6-style mistake, not micro-optimizing apex mph.
Turn-in Timing
The log doesn't have a direct turn-in/steering channel, so this is inferred from the lat-g and speed trace, not measured directly — take it as a hypothesis to test, not gospel.
What the pattern suggests:
• Your fastest lap (4) had the lowest peak lateral g (0.97) of the clean laps, yet still cleared the corner with a strong exit (84.2 mph) and the best time.
• Lap 7 spiked to 1.39g — 40%+ more lateral load — for only a marginal apex-speed gain, and it was slower overall. That signature (high peak g, not much apex speed to show for it) usually means an earlier, more aggressive turn-in that loads the tire hard early and scrubs speed, rather than carrying speed to a later apex.
Recommendation: Try turning in later/gentler — get the car rotated closer to a single, later apex rather than committing lat-g early. Based on lap 4 vs lap 7, that style is giving you a 0.12s advantage even with a slightly lower apex speed. Confirm this next session with a steering-angle or yaw-rate channel if you can log it — that will pinpoint the actual turn-in point rather than us inferring it from g-load.
