Are you joking ?
Lucci recovers while Luffy and Sento are talking, how long did those sentences last? 20 minutes lol?
At most a couple seconds. If you knock someone out then not for seconds.
Lucci being knocked out is fake news. He was never out of the fight. He immediately got up and changed target because that's the wise move.
Even Base Luffy fought equally with Kaido let alone Nika Luffy who straight played with Kaido on multiple occasions. Also, we even entered a new island and as per OP logic Luffy has now mastered this ability so he grew in power.
The Luffy Lucci is currently fighting is High Yonkou borderline PK tier.
So you are taking a durability feat as an all stat booster, following your logic King is Admiral/Yonko level easily.
ACoC doesn't boost stats other than AP/DC, Luffy base was fodder against Kaido base, he wouldn't make it past a minute without getting knocked out, but in the last round he could fight base without losing vs kaido hybrid, that alone is evidence of how weak Kaido was, plus Yamato herself emphasizes that before Luffy vs Kaido starts for the third time.
The clearest evidence that Luffy doesn't beat any Admiral/Yonko is BB indirectly admitting that he can't beat Akainu even though he's stronger than Luffy by narrative which is undeniable, Luffy doesn't beat BB without another powerup.
You just want to give Lucci a handjob to then give an even bigger handjob to the Admirals.
