The word "Puissance" in French means "power" "strenght/might"
6/6 For Zoro and Luffy (Same). 5/6 For Sanji.
@ One Piece Databook Yellow
There's one more thing I would like to add. Thanks to TBogard for reminding me lol
Again In the databook One Piece Yellow: Grand Element. Oda himself said that Zoro and Luffy has the same high fighting power. This proves that Zoro is not weaker than Luffy as the common idea goes.

Absolute trust in the captain!!
Follow the captain's orders without hesitation - this is the attitude that Zoro always has, because he has faith in Luffy from the bottom of his heart! He has an equally high fighting power as Luffy and when the need arises, he will be the first person to charge forth. Even though he has a devil-like fighting capability, he recognizes Luffy's position as the captain. Moreover, even when Luffy makes the wrong decision, he will give his best to rectify the mistake and never complains. This is Zoro's attitude.
Remember, Databooks are made under Oda's supervision "at the least". Rest you can understand yourself.
