What do you think that are the powers levels of the StrawHats Pirates? For comparing I will use Douriki.
In Enies Lobby Arc Rob Luci had the most douriki(4000). I think that Luffy had the same level of douriki since he had no power left after he defeated Luci. Or maybe just a little more Douriki.
At the end of Marineford Arc I think that Luffy's level is about 5500, maybe 6000. -> after reuniting :-O OVEEER 9000! ... for real
Maybe you can give some numbers for the rest of the Straw Hats...
