But seriously, all increases happened after something major they did that caught the government and/or Marines' attention. Nezumi being a whiny cry-baby, that little scuffle at Whiskey Peak, that little dispute with Crocodile, that thing at Enies Lobby, and then the whole war thing. So yeah, there is definitely a chance the numbers could go up after this. I mean, it involves royalty, a Shichibukai, and the Marines are there too. Granted, Oda mixed it up a bit, but the formula from Alabasta is still the same.
