And now the problem comes to not knowing what they do to choose the numbers. For Luffy's bounty after Marineford, I think it was the number of Marines he pissed of times 1000. After that I got nothing. I personally think there is no system. If you ask me, Brandnew and the rest of the Marine accounting department just sort of eyeball the bounties.
