P4P means if everything is equal. Take Shawn Porter for example, he is basically a welterwright version of Tyson without the power and skill.
Wilder is very fast and athletic. you don't think that would transfer will to Welterweight or Middleweight.
Wilder would basically be Paul Williams or Tommy Hearns without the skill. Or maybe a rich man's Indongo with power.
Williams wasn't a huge puncher at his weight though, or especially fast, so aside from the physical appearance I don't see how they're comparable. What I'd like to know is how much faster Wilder is at welterweight than at middleweight, and how much quicker is he at middleweight than at heavyweight. And how much does his power get scaled down at those respective weights? And does his athleticism increase, decrease or stay the same?
His power would be Julian Jackson level. He would be as fast as Tommy Hearns and have a motor quite similar. It's like if you made Spence a natural 160 pounder hw would be GGG
