Doing better doesnt meean 1vs1ing ,especially since the gap is that severe. training for a few days doesnt make you go from fodder to overwhelming someone. Thats the worst writting ive ever seen. Luffy couldnt do anything against kaido at all and he got overwhelmed in speed and strength and onee shot. No one has did that before, even croc didnt. All of his other fights before were the oponent wining due to hax or the difference in power wasnt that much. He couldnt hit croc but once he figured it out it was easy, because croc was only shown dominating him with his hax. As for lucci, base luffy made him bleed and he didnt one shot luffy either just threw him back. luffy was fine and dandy after that. This is diffrent, you cant compare these dudes to one of the 4 strongest pirates in the world.
If luffy 1vs1s Kaido, it would be an asspull of the highest order.
I think Luffy can 1v1 Kaido and defeat him , as long as Kaido actually doesn't have Hybrid . if he has Hybrid then Luffy could very well get assisted with Law , Zoro , maybe Kid
Luffy didn't have Observation Haki or FS though when Kaido blitzed him , which was a massive loss
Luffy wasn't calm , he was raged . Katakuri said one have to be calm for Observation Haki to work
if Luffy had Observation/FS , the fight would've been longer imo , but since he wasn't capable of hurting Kaido ( with his attacks outside KKG at least ) , it would have been a higher end of Mid Diff for ( Base ) Kaido
but now Luffy has 2 levels of Advanced Armament , right ? which Luffy himself and Hyogoro believed to be capable of hurting Kaido's insides , and passing even the most durable parts of Kaido's body ( scales )
1 type of those Advanced Armaments is the same type as the one Aokiji , Akainu , Kizaru used to block a Whitebeard's Quake , the other 1 type can hurt Kaido's insides ( as Luffy and Hyogoro believed at least )
so while Luffy was indeed 1 shotted by Base Kaido , in Fire Festival he will have FS + 2 types of Advanced Armament .
these 3 are massive power ups . Luffy went from being defeated ( and destroyed ? ) by Katakuri before FS , and post FS he was able to defeat Kata
that's why i think Luffy will overwhelm ( and shock ) Kaido in Fire Festival , though Hybrid Kaido will overwhelm him

Yes , Lucci and Crocodile can't be compared to Kaido , but Alabasta Luffy and Enies Lobby Luffy can't be compared to this Luffy either
