I'm leaning more towards 15% but 20+% in different use cases.
Plus out of all the leakers there are on anything like this while i take it with a pinch of salt, there are many many of them that simply do not have a clue what they are talking about, they see a crumb of info and go max power to infinity and beyond with it lol
The ones that have got it right over the years or at least reasonably close well pay attention to them, cause the rest of these so called leakers are, then just run with crazy ideas lol
