Home Run Proficiency relative to League.
(P-(L-P))/((L-P)
In this equation each letter represents (HR/AB) for either the player or the league minus the player. The result is the number of times the player's HR rate is better than all the other batters in that league that season.
______________________________
Read that post for the method and background. The original criteria: HR >= 35 and (AB/HR) < 12. That produced 116 seasons. Removing (AB/HR) < 12 produced 605 seasons.
In the data provided the column X represents the equation described above. Click link to view the data.
50 HR:
50 HR have been hit 42 times. Ruth has the top four X ratings, including three in which his HR hitting was ten times more proficient that all the other batters in his league that season.
14 of 42 X >3;
10 of 42 X < 2
