The annual knee percentile was derived from the smoothed profile of Total Singles Points across this TRP-based percentile ordering and was subsequently applied to the same percentile scale. Players whose TRP-based percentile position was less than or equal to the annual knee percentile were classified as elite, whereas all remaining players were classified as non-elite. The column “n classification mismatches” verifies the internal consistency between the stored elite-status classification and this annual knee-percentile rule; no classification mismatches were identified. No new elite-status classification was created for this supplementary table.</p> <p>(XLSX)</p> 2026-09-29T17:23:14Z Dataset Dataset 10.1371/journal.pone.0359538.s001 https://figshare.com/articles/dataset/_p_Annual_knee-point_thresholds_used_for_elite-status_classification_among_female_ITF_World_Tennis_Tour_Juniors_players_2004_2025_p_/34025521 CC BY 4.0
