That's not how it works
The combined strength is used to produce much bigger shockwave, Kaido and Big Mom were surprised even one of the 5 supernovas survived same Kaido who knows Luffy can survive Thunder bagua no problem.
What does exact same method have to do with strength, its a generic way to swing, its the amount of strength put into swing.
This is what Ikokou looks like
And this is what Hakai
You seriously telling me Ikoku looks half as strong as Hakai? Wanker if Hakai was launched inside skull, it can wipe out 20 of those skulls.
Talk about being intellectually dishonest.

Dont waste your time dude
Hakai is clearly put zoro durability above every supernova, and he still can injured kaido while being half dead, in this generation only garp, mihawk or shank that can stop that thing, and its the most powerful skill that appear in one piece so far
Idk about gorosei or im because oda didnt show their fighting power yet
