Cases and case writers

Some of the cases are getting on my nerves... especially the finance cases. They give you so much insufficient data, then give exhibits of cash flows without even a mention of which year it is, when dealing in cases where even the aim of the case is not clear. Statements like "the relevant market for the company is worth $7billion".... does it mean the whole market for the product is worth $7b or a fraction that the company will get? And that too for a start-up company... how can they go from zero to $7b in a year? It does make sense how. There is usually a production delay and growing to such large numbers takes years. When even interpretations of the statements have to be assumed and there is no other statement ruling out the alternative possibilities, I dont think the case is anything but sh**y. And on such statements 5 year projections of the company's worth is to be found out? Bullshit! I wonder how such confused profs. are even allowed to write/mentor cases. But then again, great theories in finance have been made made looking at random motion of pollen grains in water. Finance rocks! or not!
