Peter Elter has found clay courts difficult, recording 66–81 across 147 matches (44.9%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar. Peter Elter has reached 3 finals without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Peter Elter is 5–7 (41.7%) across 12 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

3 finals reached on clay — none converted into a title yet. Reaching 3 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 7 semifinals. 12 quarterfinals.

vs. Top 10 on clay: 1–10 (9.1%, 11 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: 6–13 (31.6%); best-of-three: 60–68 (46.9%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 1982 — 12–7 (63.2%) from 19 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
