Ha, I was in consulting for a while (not Accenture but close enough) and ran projects where we did this type of project-level profitability analysis. We wouldn't have called it "exponential", because even though you're right that we made a multiple on a person's salary that's > 1, that multiple is pretty much fixed after a certain point in the size of the company. 3x would be typical for a mid, but if I add one more incremental mid I will still expect to make 3x my total salary, so that is still a linear revenue=3*totalsalary. If that 3x because 3.1x or something as I hired more people, then yes, you get some exponential effect there, but it would only do that in extremely small consulting shops.
