All this proves is that Lucci is stronger than yall gave him credit for and that Luffy is a lot stronger than Zoro which is common sense.
How new are you to this?
Here are the rules, lad. Free of charge.
Rule 1:
If Zoro fails to defeat an enemy then its Zoros fault and Zoro is weak.
Rule 2:
If Luffy or Sanji fail to defeat an enemy then that enemy is too strong.
Rule 3:
Losing to Zoro means that the character is weak.
Rule 4:
Losing to Luffy means that the character was Pirate King level, but Luffy is just stronger than that.
Rule 5:
Losing to Sanji means that the character was automatically above Zoros level which also puts Sanji above Zoro.
You can not change these rules. They are absolute.
