In most of chapter 415:
-Jyabura uses High-speed scratch, Sanji is visibly shocked and can't react, gets blitzed.
-Jyabura uses Don Po Ro, Sanji tries to attack at the same time but gets overwhelmed in CQC, and can't even land a hit on Jyabura before he's thrown away.
-Jyabura uses Lupus Hall, and Sanji can't dodge. Gets hit and is hurt.
-Sanji gets up and clashes with Jyabura head-on. Gets overwhelmed, loses the clash, and gets sent crashing into a wall.
^^^^
All of these things happened one by one with no other event in-between. Jyabura was absolutely overwhelming and shitting on Sanji from the moment he got serious in 415.
You think suddenly Sanji got much weaker?
Or are you just an idiot who thinks Scabbards > Kaido because they overwhelmed him in early fight, just like Base Sanji- before getting shit on soon after, just like Base Sanji.
You said Sanji used DJ twice and landed both of those hits. I stopped reading and literally showed you a scan of Sanji missing the DJ because you're clearly lying from that point onward.
