Pilots grouped by how alike their flying was.
Analysis computed
The groups are flying style, and not score. The spread of ranks in each group shows where that style paid and where it did not.
10 pilots · ranks 1–14 · median 5.5 · middle half 3.3–7.8
3 pilots · ranks 9–13 · median 12 · middle half 10.5–12.5
13 pilots on 21 behavioural metrics formed 2 groups.
GlideComp groups the pilots by flying style, and not by score. It transforms the rank of every behavioural metric to a percentile inside the field. It then compares two pilots by the mean percentile gap over the metrics that both pilots have, and never fills in a missing value. Ward-linkage agglomeration forms the groups, and the best mean silhouette selects the number of groups. Each group carries the spread of the GAP ranks of its members, which shows where a style paid and where it did not.
k was searched from 2 to 4. The mean silhouette is 0.17 — a value near 0 means soft group boundaries, and a value near 1 means tight, well-separated groups.
