At Grand Slam level (Roland Garros): Allan Stone is 8–7 (53.3%) across 15 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

One final reached on clay, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 2 semifinals. 7 quarterfinals.

vs. Top 10 on clay: 0–3 (0.0%, 3 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: 12–11 (52.2%); best-of-three: 45–49 (47.9%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1969 — 14–6 (70.0%) from 20 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
