Abstract

fetched live from OpenAlex

The purpose of this study was to assess the directional accuracy of the delivery in competitive curlers. Sixteen curlers each delivered a total of eight stones to three target locations with different combinations of rotation and speed. A laser device located near the ice surface was used to determine the line of delivery, and Dartfish was used to measure the position of the stone relative to the line of delivery. Comparisons were made at specific events: setup, pull-back, release, and after release. The results indicated significant main effects for target location (p <0.001) and for turn (p <0.001) but not for speed (p = 0.341). Post-hoc analysis revealed positional differences in the stone between the setup and pull-back phases and the release and after release phases. This information will help curlers to improve their accuracy during the delivery.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
