These are the current world sales and market share % up until now. Each future week that follows on the sheet (numbers are in blue) calculates the previous seven weeks sales averages for the entire world. This sheet is trying to predict and chart what sales will trend like based on the previous sales. Seven weeks into the future this sheet is averaging the averages, no weeks are exactly the same. So IF sales average exactly like the previous seven weeks then this sheet will show what the sales and market share will be.

 

Once November hits I used an average of historical % increases that past systems have had and applied them to calculate the sales for November and December. The same formula applies to all three systems.

 

These numbers are close to a lot of people’s predictions, and I feel they will be one of the closest ones out there.

 What are your thoughts on how this year will end up?
