I know it's quite difficult but I'd like to know the power level order between the Straw Hats. Currently I am assuming that the order is something like this:
I'm aware from place 4 onward it gets really difficult, but maybe some hints exist. For example, Oda said that Usopp's current power equal that of Zoro before time skip. That would be a good example of a great hint.
Some measurements could be the opponents they have faced, their individual power, devil fruits and for those that have it, their haki.
