Level 2 - Introduction - Lesson: Project Stakeholders

Hi

I have just started Level 2 - Introduction.  I have read that the SKU of products will be used in this level and wanted to refresh my memory with Level 1 SKU imports.  This is when I noticed that the SKU in Level 1 exam file is EN for all of US, UK, Canada and Australia.  File attached.  Was it meant to be like this?

The second question is the lesson states Initial Demand Forecast is based on Historical values being adjusted for growth rates.  Again the lesson says Historical values are based on per SKU per WEEK and the growth rate assumption is based on per product family per MONTH I am not sure whether it was meant to be like this?  May be it really does not matter? Please enlighten me.   Thank you 

Regards
