DrSham is correct here, only the 21 common songs count towards the total ranking.
Only the 21 songs count towards the displayed global total, but if you look at the top of each group of 5 it totals all of the points regardless if theyre one of the 21 global songs.
I found a bug, the #2 ranked player in that game is displayed to have 19/21 100%'s, when he clearly has a FGFC.
