We don't know the true power levels of anybody because power levels aren't a thing in-universe. As for power level discussions in the fandom, they will take into account any and all conflicts that occur. You can see that by looking earlier in this very thread when people were talking about Doflamingo's power level based on him kicking Fujitora's sword. What you're doing is making excuses for a power level argument that hasn't even happened yet. At least wait until the fight's actually started before claiming something does or does not provide an advantage.
Matter of fact if Blueno was in this tourney he would have an advantage because of this bullshit ring design. After the tourney is over an Burgess loses we can't say its because someone was stronger than him right?
