I believe Zoro will do something more before the Arc is finished and then it's the usual
Zoro = 60 % of Luffy
Sanji = 55 % of Zoro
For example if it follows this pattern
Luffy 4 billion (new official yonko)
Zoro 2.4 billion (new official vice captain)
Sanji 1.32 billion (top yonko commander)
Obviously it can diff a little for word plays and so on but in general I think that might be it. Luffy also received lower bounty than Crocodile (true worth at least 162 if not frozen according to Oda) and Doflamingo (true worth at least 680 if not frozen according to portrayal)
