95% of episodes end with the action frozen

Xense/optical-module-insertion-0731, measured from the public release on 13 September 2026. frame level, every row read

We read every frame of Xense/optical-module-insertion-0731, 198 episodes and 742,202 rows at 30 fps. 95% of episodes end with the commanded action no longer changing for ten frames or more, 98% for at least one frame, and the longest run is 3.77 seconds. We measured the same property on eight public corpora and the rate tracks how the data was produced rather than the task, so it separates scripted takes from human ones.

How each episode ends

A trailing hold is the number of frames at the end during which the commanded action does not change by more than 1e-4 on any component. Seconds come from the frame rate the release declares.

The release is a meta directory plus one or more parquet files. Read data/chunk-000/file-000.parquet, group rows by the episode ranges in meta/episodes, and compute the same columns. No credentials.

What a full grading adds

This page is what a published release will tell you on its own. The full grading removes the part that scores worst and retrains on what is left, then reports whether the smaller corpus scores higher, with rollout counts and intervals. The one result measured on physical hardware is Stera-10M, two arms on a four arm SO-ARM101 bench, 21.9% against 36.9% task success across 1,270 rollouts.
