Amateur-era peak came before the Open Era

Her best Grand Slam result in the Amateur Era was a semifinal, plus one quarterfinal, both before the Open Era entries begin. In the Open Era, her top result was only one quarterfinal, so her deepest run came earlier.

1977 was her busiest and strongest Open Era season

She played five Grand Slams in 1977, more than any other year listed, and reached her Open Era peak with a quarterfinal at the Australian Open (Dec). The same season also produced a round of 32 at the US Open and round of 64 finishes at Wimbledon and the French Open.

Her career stretched across two distinct age peaks

At age 20 she reached the Wimbledon semifinal in 1967, then at age 30 she reached the Australian Open (Dec) quarterfinal in 1977. Those are her two deepest results by age, separated by a decade.

She was consistently competitive but rarely beyond the early rounds

Across 18 tournaments and 48 matches, her record was 30-18, a 63% win rate. Yet most results clustered between the round of 16 and round of 128, with only four appearances at quarterfinal or better.

Her final two Slam appearances were both first-round exits

In 1978 she lost in the round of 128 at both the US Open and Wimbledon, both at age 31. That marked a sharp drop from the previous year’s quarterfinal and round-of-32 results.
