Forum:Why didnt straw hat pirate bounty go up after movie 10?

Shiki is known as one of the old and strong pirates during gold rogers time just like white beard so why hasn't the Straw Hat Pirate crew's bounty go up after the battle? The marines already know they took down Shiki. This just proves that Straw Hat Pirate should be as strong as sengoku and garp combined since it took them two to fight Shiki since it says it on the page that those two fought against Shiki.
