Observed writing choices, not acceptance rules. This study examines the inspected manuscript version. It does not establish why the paper was accepted or that its presentation choices should be copied unchanged.

Figure, table and section ledger

Editorial contribution type: Architecture & representation (primary).

Layout extraction, not a required paper template. Counts are distinct caption labels; a multi-panel figure counts once. Section spans are estimated from heading positions, including floats and whitespace. Method and limitations.

Extraction notes: No attached appendix boundary detected. Zero means no recognized caption, not independently verified absence.

Section-by-section lengths and source pages

The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

Argument and organization

1. Problem and contribution

   Separates position accuracy from plausible velocity and acceleration, motivating why low joint error can coexist with unnatural motion.

2. Argument sequence

   Introduces initialization, PVA prediction and global optimization before separating static- and moving-camera evaluation.

3. Evidence and verification

   Table 1 pairs each base estimator with its refinement and reports jitter, foot sliding, dynamics and global errors, so smoothing is not mistaken for complete improvement.

Tables, comparisons and evidence

Table 1 pairs each base estimator with its refinement and reports jitter, foot sliding, dynamics and global errors, so smoothing is not mistaken for complete improvement.

Appendix and reproducibility

The supplement reports velocity/acceleration prediction separately from full refinement and supplies architecture and optimization details.

Clarity and writing conventions

The results explicitly discuss foot-sliding and position-metric exceptions rather than interpreting every smoother sequence as better.

What to reuse—and what not to infer

Transferable lesson: If the contribution targets temporal realism, add dynamics-specific metrics and verify that static accuracy is not traded away unnoticed.

Boundary: Reduced jitter can also arise from oversmoothing; retain acceleration fidelity, contact behavior and positional non-wins in the narrative.

Apply this lesson using the argument and evidence worksheet.
