I wasn't all that wowed by Mark & Paige's dance. They did well, but they had a good song to dance to. I was more touched by Mark's reaction afterward. I'm glad Tom picked up on it and had Mark speak. But, I'm sure having Mark's fiance as their singer also affected him.
As for Nyle's dance, maybe it's because I was so affected by it, I don't care how many people went into creating that dance. When I see a play or movie, I know there are a lot of people who went into creating it. But, the performances still belong to the performers.
And yes, Robin, that's like comparing apples to oranges

and not what you are referring to. It does make a difference that the guy who conceived, wrote and now stars in Hamilton, did it all himself. And since we are talking about judging a whole performance, that stuff does count. I know I'd factor it in at another instance.
