Markstrat - How are the revenue figures computed by the marketing plan?

QUESTIONS: 

There is now no need to enter the distribution mix in the marketing plan. Yet, the revenues in the proforma statements must depend on the distribution mix since margins and discounts vary across different channels. How are the revenue figures computed by the marketing plan?

ANSWER: 

If the team ordered the "Consumer survey", then shopping habits are used.

If not, we use the average brand margin of the previous year for existing brands and we use the average firm margin for new brands.

This is perfectly fine for Sonite, but a little bit underestimated for Vodites.
