Peak run came in 1970

Her strongest Grand Slam season in the data was 1970, when she reached the semifinals at both the Australian Open and French Open and the quarterfinals at Wimbledon. That is the only year with two semifinal results.

Australian Open was her most productive major

Across seven Australian Open appearances, she produced one semifinal, two quarterfinals, one round of 16, and one round of 64 result. No other Slam shows as many deep finishes in the table.

Best results clustered between ages 22 and 28

Her top-level Grand Slam results all came from age 22 through 28, including the 1970 semifinals at age 23 and 24 and the 1974 quarterfinal at age 27. The lone 1977 semifinal came at age 31, outside that main peak window.

Strong Open Era record, with one Amateur Era appearance

Of her 22 Grand Slam tournaments, 21 are listed in the Open Era and only one in the Amateur Era. The Amateur Era entry is a 1968 Australian Open quarterfinal, while her Open Era record is 63-22 overall.

Wimbledon and US Open were less consistent than Australia

Wimbledon produced one semifinal, one quarterfinal, one round of 16, and three round-of-64 exits, while the US Open never went beyond the quarterfinals and included two round-of-32 and one round-of-64 result. Both were shallower than her Australian Open profile.
