The tracking period appears to be Friday to Thursday, I did not know this. Logically this would mean Friday 00:00 to next weeks Thursday 23:59. This actually makes it A LOT better for IVE. Don't want to prematurely celebrate but IVE had a solid lead in the 'last 2 day streams' at the end of last week and it's been held for the entire tracking period so far, I believe. Even if the difference in streams is shrinking down to nothing now it probably wont be anywhere near enough to change the #1 weekly streams.
Ooooh that's great. Even if it's one single PAK, I'd take it tbh
