The video does not claim that this principle is the perfect one.
It just asks for it.
I have a strong beef with the word "Perfect".
There is a difference between asking for perfection and striving for it. Asking is meaningless, since it implies you're waiting for an answer. Striving means work, indulgence, dedication to something that is achievable. Do I think perfection is achievable? No, not the empty, esoteric perfection, which I think is a meaningless goal ( ever heard the "no one can perfect a sleight"? ... Its not about if you can or not, its about the mentality, this is just not how it works ).
I go with the artistic perfection, which can still be taken in so many directions and ( ironically) can be improved upon. A Leonardo Da Vinci quote Vernon used often describes it: "Perfection has no details",it refers to the harmonious accumulation of details and generics to produce a seemingly unified beautiful product, like a well studied magic trick, and while it can be looked at as such, it can be still be improved over and over again, and even varied if it falls in the hands of a magician with different artistic choices. Ascanio's O&W vs Mike Skinner's. Peter Kane's original Jazz Aces vs John G. or Jack Parker. Its about reaching whatever artistic goals you strive for, which perfection is not one of them because its just a senseless goal with no clear objective. See performances of people like L.Green ,Temariz, Derren Brown, Darwin Ortiz or David Williamson,all "taste"differently. Its about artistic choices, goals, then striving to achieve them (resulting in an actual achievement ). When its beautiful, it becomes perfect in its own inherent way. ( On a side note: which can still be imperfect!) (I'm hoping I'm using the right words .. I'm not a native speaker, and I'm REALLY dizzy )
Thats for the "Perfect" segment ..... Now for you're video. Don't care if the below hits your point of not. This is my opinion on whats going on.
Perfect ACR phase. I personally think its the wrong way for looking at it.
A) If you take it from a method-point of view, Thurston said that no method is perfect because there will be no satisfaction in performing it. One of the satisfactions in magic ( and one of its many unique points ) is covering the imperfection of the method with presentation ...etc. Plus, magicians often refer to good methods = look flawless+foolproof and so easy that it executes itself, obviously 99% this is not the case. This is the reason many people get disappointed if the method is so simple/bold/whatever. They wont try to cover the imperfections with things like misdirection,timing, showmanship, and at the end miss the point of art of magic. An extremely bold trick can fool a hundred or wont fool a single, depending on the one doing it.
Why am I saying all this? You're mentioning the "perfect ACR technique". The criteria of what making it perfect ( and I'm making an educated guess ) are flawed. Each technique/principle has its own place and merits.
B) If you're looking at it from an effect point of view, it yet achieves a worn-out ACR phase, with the added bonus of making it more convincing than the others. In the end, its just that. It falls as a stand-alone, it might go well as a first phase in ACR but then again, an ACR with cards jumping to the top bazillion times is nothing to be called "perfect", its simply boring.
In other words, saying "perfect" in your video is flawed, because if its a technique, no technique is perfect, each has its own place. If its an effect as a clean ACR, its not perfect, just a good one. Why not perfect? see the previous paragraph.
But regardless if its perfect or not, I think the whole idea of perfection in this vid is senseless, falling under the empty type of perfection I talked about in the beginning, which is why I explained my beef with "Perfection" in the beginning.
S***, that took a long time to explain. If the above doesnt have anything to do with the vid, then I apologize for everyone for reading my none-sense.
Off to sleep .............
