I think one of those estimates was too exaggerated, when Carlo died it might have been 250 to 300 made guys, especially with 25 Crews, average of 10 men x 25 crews is 250, plus the captains and administration.

But aside from that point, I have a bigger question to ask about New York:
1). What did a Crew receive in return for giving Paul 15%?

2). How did Paul possible know if he was really getting 15%?

3). If the Crew did not really receiving any benefit from Paul and he had nothing to do with them making money, why did they need to give him 15%?
In Chicago, the Boss made money for a REASON.
