In what year do you see a warning sign for channel stuffing?
How many dollars of sales do you estimate were "stuffed"
into the channel without being ordered?

For this question, i was given the net sales and account receivable. I was asked to calculate the annual growth for sales and percentage of AR to sales. My answer to that is provided. I am stuck on the last two questions. "In what year do you see a warning sign for channel stuffing?" and "how many dollars do you estimated was stuffed?" Explain both answers. Thank you.
