Was their total bounty 200 mil or 400 mil?
^^
444,400,000 could be one of Sanji's later bounties but I highly doubt it.
Due to Moriah's ties with Kaidou I can see this being Kaidou's bounty.
850,000,000 could be Zoro's EOS bounty.
I'll be honest with you it does in some cases make sense. So you know Luffy's Gladiator number... 556...
Dorry = 100 and Brogy = 100
the number 100 can be looked as a hint to Luffy's next bounty and\or 200 as a hint to someone's bounty.
Enel's attacks that include numbers are 30 million and 60 million are also something of some connect to bounties Usopp = 30
and Zoro's previous = 60 which later doubled..
as for Kaidou's bounty. It probably could.
the number 560 million that assumed to happen as Luffy's next bounty because he challenged Ace to be Pirate King.. and it happened to appear on Luffy's clothe in the 3D movie "Gomu 56" and in SBS about StrawHat's numbers..
take the numbers on T-Shirts in Davy Back Fight about the skating match too.
the order of arrivals to Shakky's cafe after 2 years.. Hilariously Zoro as first and his number is 1 ...
Saint Charloss shouting 500 million in auction on Camie..
man.. too many numbers here and there and you re-read and re-watch ONE PIECE looking for numbers everywhere.
