OK guys, there are some things that I believe I have figured out about the formula. So here goes nothing...
• Paid Promo - Since in each chart, the amount of points you get is on a x10000 scale for the chart (Ex. 15 Points = 150.000 sold) I believe that the amount you pay for a promo slot is an automatic sales garuntee. (Ex: Ellen / 5 Points = 50.000 sold)
• Touring - Like with the paid promo, I think for each date you perform at you autmoatically sell 30.000 copies per date because it costs three points to have a date
• Campaigns - Confirmed by RS on Twitter: Ads/Endorsements are likely to earn you more points than regular promo shows
• Magazines - My guess is the amount of copies sold is in between regular promo + campaigns
• Regular Promo - (Ex: Conan, Jay Leno, etc.) It could probably earn you like 10.000 - 20.000 depending on interviews, etc.
• Concerts - RS confirmed in a tweet once that a concert could sell anywhere from 60.000 - 100.000 depending on the concert
• Album - For an album, I think the promo you've done will be calculated, then divided by a number because albums are harder to sell than singles
These are just my guesses/what I know. Hope you guys find something useful out of it
