I think it's contextual. I don't model the entire person, just the aspect of that person in which I see excellence. No one's going to occur as being excellent in every single way, and there's no reason they *should* -- and that doesn't make anyone any less magnificent.
If I'm modelling someone I don't know personally, like a celebrity or someone from the past (or potentially, the future), I recognize that it's my own unconscious projections of excelence I'm modelling, and that's fine. My unconscious mind has access to all kinds of wealth of resource that can benefit me consciously, so that kind of modelling can be very, very helpful, too.
