Let me do some equation used by certain people here
Ikkoku sovereignty is half of Hakai and Kidd tanked it fine along the all other attacks he took from Bigmom+Hawkins+Kaidou prior to the fight. So more or less, that is some crazy endurance or durability feat from Kidd without breaking his bones. Based on this math, I think Kidd can block Hakai 2 or 3 seconds more than Zoro. Kidd right now has highest durability feat from an alliance side. Dude, didn't even take rest and eat meat or senzu bean to magically recover.
