At Grand Slam level (Australian Open & US Open): Dominik Koepfer has struggled at Grand Slam level on hard: 6–10 (37.5%) in 16 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): Dominik Koepfer is 7–8 (46.7%) across 15 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole hard swing.

2 semifinals on hard without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 5 quarterfinals adds further depth to that picture.

vs. Top 10 on hard: 0–11 (0.0%, 11 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: 6–10 (37.5%); best-of-three: 31–33 (48.4%). 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: 2023 — 7–5 (58.3%) from 12 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
