Knee sweep
120 deg
Average left/right knee angle range in the processed clip.
Middle-distance reference
Ingebrigtsen's sample is not the cleanest file in the set. It is useful because the page can show where a reference clip is still worth keeping, but should be treated with caution.

Efficient carriage with moderate knee lift, a stable rhythm proxy, and weaker foot visibility than the cleaner clips.
These are clip-derived signals, not a coaching diagnosis. The point is to show what the pipeline can read and where the video still needs review.
