This is "a whole lot of evidence". If he had, for example, a 10% chance to show up suspicious in any one of those charts that's one thing. But to be highlighted as the most suspicious in each is extraordinary evidence. How do you explain a greater than 10% drop in skill when a 15 minute TV delay was put in place? Or his ability to make incredibly complex, perfect moves in seconds? Or his continual, nearly unstoppable strength rating growth, you know, except for the two natural plateaus in rating where most players never continue to grow firmly in the middle of his growth curve?

If that report doesn't convince you, I doubt anything will.

If he always did what the engine tells him to do then the evidence would be overwhelming, yes. Hans is surely aware of this and avoids doing so because he wants to get away with it.
