Billboard (BB) used different methodologies in different years to calculate the year end chart. From 1962 through 1986 they were based on a simple inverse point system (100 points for #1, 99 points for #2, down to 1 point for #100), referred to as reverse rank. 1962 through 1966, and 1969, no bonus points we awarded. Beginning in 1967 and through though the 70s and early 80s bonus points were awarded for #1 songs. Beginning in 1984, top 10 hits also received bonus points. In 1987, BB changed to a complex inverse point system which was used until Soundscan in 1992.
Without #1 bonus points, non #1s with longevity were able to outrank all the #1s in some years. Had #1 bonus points been awarded in 1965, "Satisfaction" would have been #1 for the year instead of "Wooly Bully". For 1963 either "He's So Fine" or "Sugar Shack" would have been #1 instead of "Surfin' USA", depending on the cut off. BB's revised version for 1966 awarded bonus points, putting "The Ballad of the Green Berets" at the top instead of "California Dreamin'".
