Jerome Potier has found hard courts difficult, recording 20–25 across 45 matches (44.4%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Australian Open & US Open): Jerome Potier is 3–4 (42.9%) across 7 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

6 quarterfinals on hard — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on hard: 0–3 (0.0%, 3 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 3–5 (37.5%); best-of-three: 17–20 (45.9%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.

Best season: 1981 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
