At Grand Slam level (Roland Garros): Tomas Smid is 15–14 (51.7%) across 29 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

17 finals reached on clay — won 4, lost 13 (24% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 31 semifinals. 55 quarterfinals.

vs. Top 10 on clay: 8–31 (20.5%, 39 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 27–25 (51.9%); best-of-three: 239–119 (66.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Dominant season: 1983 — 38–12 (76.0%) from 50 matches. A campaign of 38 wins on clay in a single season is among the best single-season records the surface has seen — the clearest benchmark of what is achievable at peak level.
