No we don't, not after we were told Kizaru fed Luffy after taking WSG and then lying back down so that he could fake it. But regardless, I already told you this is irrelevant, nobody sane should place Mingo below DR Luffy, and Mingo didn't put a scratch on G4 and was actually portrayed clearly below G4 far more than Kizaru was against G5. Kizaru was never fighting to kill in the first place. Just going in circles now.
Now you're just getting into complete headcanon territory. Blackbeard looked more compromised against Law than Kizaru ever did against Luffy in round 1 before Oda made it obvious Kizaru was mentally out of the fight.
Oda did more than enough to show Kizaru was not in the fight during Egghead. I think he didn't want to show the food scene because it was a bit too embarrassing for Luffy, so I will say he did protect Luffy's image there. But we know what he actually thinks now.
