Thanks Pete. I see that schedule and see the last weekly show was recorded on Dec. 11. Both that and the year end show were shipped on Dec. 13. So my scenario really doesn't work about "You Light Up My Life". The only way to get that at the #1 position for the year is in 1978 whereby they based points on the entire chart run. Thanks also to CRZ who seems to have pointed out that said policy did not start until 1985.
vince, did you do the calculations for the top 50 of the 70s? There were a few questions I had about that such as why the Bee Gees 3 hits from Sat. Night Fever were in the reverse order of how they ranked in the top 100 of 1978. I also wondered why the songs that were 2,3,4 and 5 in the top 40 of 1973 did not make the top 50 of the 70s yet the songs at 6,7,9 and 11 did.
Dukedeb,
I was not able to figure out any mathematical way AT40 could have come up with their ranking for the Top 50 of the 70's. They may have used a correction factor to give more weight to songs in years with smaller hits a better chance. There are still a lot of discrepancies such as “One Bad Apple” ranking higher than “I’ll Be There” when they were hits about the same time and I’ll Be There was on the chart longer. There was also “I Just Want To Be Your Everything” ranking way below “Best Of My Love”, which could be explained by #1 bonus points, but then why did “Night Fever” rank below “Shadow Dancing”, and “Stayin’ Alive” and “How Deep Is Your Love” rank higher. It was also very unusual the “Killing Me Softly” that was #1 5 weeks didn’t even make the top 50.
I did compile my own Top 100 of the 70's based on the Hot 100 if you want to see how the songs stacked up without a correction factor. The frozen weeks were not counted and non-#1's were included.

Regarding the examples I posted earlier with 1978's top 10, I used BB’s survey period that was 11/5/77 to 10/28/78. “You Light Up My Life”, “How Deep Is Your Love” and “Kiss You All Over” had a major part of their run runs cut off. YLUPL would have been the #1 of 1978 if its entire chart run was counted.
