I don’t think this site “tracks” anything anymore, back in the day ioi would get data directly from some retailers and had a specific methodology to extrapolate based on that.
Now I think we just wait for whatever official data gets released like fiscal reports, Circana, Media Create, etc and basically guess for the regions we don’t get any data for.
