Did you notice billboard gave us some useful information. We can find Hot100 point changes in a few cases so we are able to find Hot100 formula.
I used this equation:
Points=A*sales[k] + B*streaming[m] + C*IA[m].
where A,B,C are parameters in % with 1% step(0, 1, 2,...) and A+B+C=100%.
There is aprox. 81k potential options so I wrote special programme. And only one formula works:
points=4%*sales[k]+91%*streaming[m]+5%*IA[m].
We can multiple te equation and find another fulmula's form:
Points=4*sales[k]+91*streamin[m]+5*radio impression[m]
Ok, so let's check:
#1 Roar: 4*448+91*5.4+5*97=2768
#2 Blurred Lines: 4*244+91*6.7+205*5=2531
#3 Berzerk: 4*362+91*2.7+5*21=1799
#4 We Can't Stop: 4*157+91*8.1+5*57=1650
#5 Holy Grail: 4*170+91*4.6+5*89=1544
#6 Applause: 4*213+91*4.2+5*39=1429
We must remember if sale figure is 448 real sale is between 447,500 - 448,449. My soft calculate this doubt(first when i forgot about it any formula don't works).

I'm pretty sure this post deserves a medal or something. Everyone needs to recognize.

This chart week
. Katy at #1, Avril's debut above the peak position of "Hot", and a new peak for "American Girl"! It would be even better if Drake was in the top ten already, though. Lots of other good stuff going on too, I'm sure.
