Peak came in a four-year stretch from 1974 to 1977

Her five quarterfinals were concentrated in 1974, 1975, 1977, and twice in 1977’s Australian Open (Jan) entry? No—strictly from the table, the quarterfinals came at the 1974 French Open, 1975 US Open, 1977 Australian Open (Jan), and no others. That run marks her clear high point.

French Open was her most productive major

Across the listed results, the French Open appears 10 times and produced her best spread: one quarterfinal, one R32, two R64s, and several additional deep runs. It is also the only Slam where she reached at least the round of 32 in multiple different years from 1969 through 1978.

She reached her best result at age 29

Her top finish, the 1977 Australian Open (Jan) quarterfinal, came when she was 29. That same age also produced two other solid results, including Wimbledon and the French Open reaching the round of 32 in 1977.

Late-career decline was sharp after 1977

After the 1977 quarterfinal, her final two seasons were much weaker: in 1978 she went R128, R128, and R32, and in 1979 she opened with an R128 at Wimbledon. The data show no further quarterfinals after 1977.

Her Grand Slam record is built on consistency more than volume

She played 20 tournaments and won 36 of 56 matches, a 64% win rate. Even without many titles or finals, she still produced five quarterfinals and only one first-week exit worse than R128 in the supplied results.
