Like for 4, your score 10.5144 but according to your methodology:
BB200: #1 = 10 pts (plus extra for multiple weeks at #1 and extra for 43 weeks charting)
Hot 100 = 25 pts (plus extra for however long the songs spent on the Hot 100) [Top 20 = 10 pts x2 = 20/ Top 40 = 5 pts]
Accolades = 3 pts for LOT genre Grammy win (plus more for other moms/ wins IDK about)
Should give 4 at least 38 points, plus all of these supposed "extra" points... So where does the 10.5144 come from?
It functions like the Billboard Hot 100 formula.
Each girl got points like you said, on each fiel (albums, singles, awards). But for the final score they were weighted differently.
