Top 20 by Peak Quality

.
"Peak Quality" is the highest average in career points over 8 tournaments (= 2 years) that a player piled up, and therefore a measure of dominance at the player's career peak. The statistic tends to bias against players in the 1970s who often did not participate in all four Grand Slam tournaments (notably, many skipped the Australian Open).
