What exactly is the average "market share of the industry"? In simple terms, what is this? The market share of the average player? Arithmetically, is this the arithmethic average of market shares of all players in the region or what? Very confusing at first sight and not sure how it is relevant in the case. If my understanding of what it means is correct, then this metric just shows fragmentation of the market in different regions, which then contradicts some of the guidance in the answer of the case. I'd suggest to make it clear - in the case and in the guided answer - what it means and what the logic in assessing it is.
