"I think that link you posted is for SoundScan of Canada"

Yawn. Soundscan is the official method of tracking sales of music and music video products throughout the United States and Canada. So even if some of the wording is different, why wouldn't the below 50% rule apply in Canada and not the US?

Here’s a link to Nielson’s US venue sales procedure and it
says

“Product that is sold at 50% below manufacturer’s list price at a venue will not be processed” That's universal for Nielson soundscan

"The same bias media never tell people that SOUNDSCAN only count physical cd’s and not digital sales."

She said nothing about first week sales and neither did I. where in that sentence did she say "first week sales?" Where in Symone's entire 5:43 post did she say she was referring only to first week sales? I reposted that soundscan link because symone said that soundscan didn't count digital sales AT ALL. why don't you try reading more carefully next time.
