I know a lot of people use Luffy's feats in base after awakening ACoC compared to how he was faring in gear forms prior against Kaido to say it does.
What's your take on that
I think it's simply him getting stronger and faster as the fight progressed.
Again, he went from still being grazed by base Kaidou to dodging hits from Hybrid Kaidou and landing blows on him.
I think Luffy with his gears were obviously superior though, considering how G4 was nearly going toe-to-toe with Hybrid Kaidou up until Guernica's interruption.
But maybe Haki really does amp your speed, I wouldn't really be surprised tbh.
