The new rule was introduced both for men's and women's events: not more, than three competitors per country were allowed to enter the all-around finals, if qualified [1] This was a controversial decision, which prevented many gymnasts of strong teams (the USSR in the first place) from competing in the event.
In tables below "C" stands for "Compulsory exercises" and "O" stands for "Optional exercises".
Score computation examples:
Individual all-around. In the "Team competition" event Mitsuo Tsukahara's total "C" value was 57.40 and his total "O" value was 58.35. Hence his "Prelim." value is (57.40+58.35)/2=57.875. His "Final." mark, which is the sum of marks for FX, PH, RG, VT, PB, earned in the "individual all-round" event final, is 57.70. And his total score for "Individual combined exercises" event is "Prelim."+"Final."=115.575
Floor exercises (for other apparatus events computation is similar). In the "Team competition" event Nikolai Andrianov's value for FX was 9.45, and his "O" value for FX was 9.85. Hence his "Prelim." value is (9.45+9.85)/2=9.65. In the "Floor Exercise" event he then scored 9.80, which is his "Final." value for FX. And his total score for "Floor exercises" event is "Prelim."+"Final."=19.450
Team competition
Team score for each of the routines is the sum of scores of all team members in that routine, except the lowest of them, which is discarded. Total team score is the sum of team's scores in the routines.
In tables below "C" stands for "Compulsory exercises" and "O" stands for "Optional exercises".
Score computation examples:
Individual all-around . In the "Team competition" event Nadia Comaneci's total "C" value was 39.35 and her total "O" value was 39.70. Hence her "Prelim." value is (39.35+39.70)/2=39.525. Her "Final." mark, which is the sum of marks for VT, UB, BB, FX, earned in the "individual all-round" event final, is 39.75. And her total score for "Individual combined exercises" event is "Prelim."+"Final."=79.275
Floor exercises (for other apparatus events computation is similar). In the "Team competition" event Nellie Kim's "C" value for FX was 9.80 and "O" value for FX was 9.90. Hence her "Prelim." value is (9.80+9.90)/2=9.85. In the "Floor exercises" event finals she scored 10.00, which is her "Final." value for FX. And her total score for "Floor exercises" event is "Prelim."+"Final."=19.850
