Antony Dupuis has found hard courts difficult, recording 40–60 across 100 matches (40.0%). 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): Antony Dupuis has struggled at Grand Slam level on hard: 4–9 (30.8%) in 13 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Antony Dupuis is 4–6 (40.0%) across 10 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

8 quarterfinals on hard, including one run to the semifinal — 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: 4–9 (30.8%); best-of-three: 36–51 (41.4%). 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: 1999 — 8–6 (57.1%) from 14 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
