Summary
Left-side approach
12 steps
Bar: 1.75m cleared
Miss at 1.79m (heels)
What is working
- Approach speed is sufficient for 1.80m+.
- Takeoff angle is in-range and consistent.
- Arc is smooth through the mid-curve and produces rotation.
What is limiting height
- Lean initiation arrives late (rotation occurs too close to takeoff).
- Penultimate loading is under-built (COM drop is low at higher bars).
- Descent begins while heels remain in the bar plane (glide-down signature).
Clear path to next height
- Move lean initiation two steps earlier in the curve.
- Increase penultimate COM drop by 2–3 cm with stable posture.
- Reduce “descent-above-bar” time below 0.07s to protect heel clearance.

| Bar (m) | Bar (ft/in) | Attempt 1 | Attempt 2 | Attempt 3 | Notes |
|---|---|---|---|---|---|

| 1.72 | 5'7.75" | O | — | — | Stable curve. Takeoff distance consistent. |
| 1.75 | 5'8.75" | X | O | — | Make on attempt 2. Hips clear +4.2 cm, heels +1.1 cm. |
| 1.79 | 5'10.5" | X | X | X | Misses driven by heel contact. Descent-above-bar increases to 0.14s. |

Penultimate length

Takeoff step length
2.61 m (short)
Miss sequence shows reduced drop and a shorter, more rushed takeoff step.
Vertical Trajectory

Make vs Miss Comparison
Best make (1.75m) compared to first miss height (1.79m).
Outcome deltas
Miss height shows reduced loading and earlier descent while heels remain in the bar plane.
Side-by-side table
| Metric | Make (1.75m) | Miss (1.79m) |
|---|---|---|
| Takeoff distance from bar | 0.94 m | 0.90 m |
| Lateral offset | +0.16 m | +0.22 m |
| Takeoff angle | 19.7° | 19.1° |
| COM peak height (relative) | +0.76 m | +0.78 m |
| Heel clearance margin | +1.1 cm | −0.8 cm |
| Rotation completion | 91% | 86% |
| Landing drift (right) | 0.38 m | 0.44 m |
The miss is driven by heel timing and drift, not by a lack of peak COM height.
