Actually, how revenue translates to profit is very straightforward, there are very simple formulae depending on the accounting standards the company complies to.
Also, it's not statistics that hide important information. It's just that there are many people that are unable to understand and interpret the numbers.
Ehm, not really understanding your point here...
If Company A has a revenue/turnover of 100K and 10K costs & Company B has a 100K revenue/turnover and costs of 90K then Company A is in a muuuuuch better position (90K profit) than Company B (10K profit), even though their revenues are the same.
So 'translating' revenue to profit has nothing to do with a formula, but on subtracting your costs... Unless by a formula you mean Revenue - Costs = Profit, in which case I agree. Though that would suggest that you misinterpreted my use of the word 'unknown' in my previous comment. It is not because I don't understand this basic principle but that we only know PSN's revenue, not it's costs, and therefore not it's profit, and therefore the we're stuck with the mini-skirt...
Unless my understanding of the word revenue is incorrect, in which case I apologise in advance :)
