12 of 13 champions have a recorded seed; missing values remain separate.

Age is calculated at the start of the edition. A campaign without dropping a set is included only when every match played by the champion has identified sets; walkovers do not count as matches played.

Historic comebacks

Largest deficit overcome: 0–1 in sets

Only completed matches are considered. A comeback from 0–2 requires a verified sequence of three won sets; retirements are not treated as complete comebacks.
