This may sound harsh to you, but please keep in mind that, the more we coddle someone, the less likely it becomes that the person will truly be able to understand the flaws in his performance. Coddling someone only patronizes them.
Think about this would you please. The post on your youtube page, the posts on this forum, all agree that your ACR is extremely flawed. The posts for the most part did not go into too great of detail as to how it is flawed, but some good points were made which you completely dismissed, and or blatantly said were wrong.
The movement of the card box is necessary you claim. To a spectator however, they would think, "if it is in the way, why did he put it there in the first place." Or perhaps, "why is he making such a big deal out of moving a card box so that it is not in the way," and finally! my favorite! "if the box was in the way to the side of the mat, how is it not in the way between his two arms close to his body where I can conveniently not see it anymore due to the fact his arms are covering it?"
So, I understand from your point of view how you say, the box goes one way, but the deck goes the other, so it is perfect misdirection for card to under box... however, theory and actuality are greatly different, and I suggest you take a look at...

It is all in Japanese, but starting from around 1:35, you will see his Card to under box. He does it quite well, not perfect, but very well. As you can see from the beginning of the trick, he spreads the cards on the table several times, and "accidently" hits the card box with his left hand several times while doing so, adding the perfect cover for his plant (w/o any unneeded movements).
Getting to your crazy spazmatic movements now. You claim that there is reason for them. Yes, there could be reasoning behind the movements. But honestly, if I had never met you and I saw this performance, I would think either, "this kid has ADD," "this kid had too much caffein before the show," or "he has parkinson's disease and can't keep his hands still."
Your job as a magician, is not just to assume that your actions will go unnoticed, and your job is to not just "believe" what you think the audience will think about your actions, so that you can justify your hand movements. Your job is to LEARN human behavior, and adapt your routine to MATCH human behavior and psychology.
Trust me. I know you will want to discredit everything that is being said to you because you have worked a long time on this routine. But, please don't. We are not attacking your technique or choice of techniques. We are not attacking your skill as a magician. We are telling you that there are things about performance that you are gravely misunderstanding.
My biggest pointer to you is. Do not change your routine. Work on each phase until it is perfect. Until you can do all the sleights 99 out of 100 times perfectly, so that your hand movements will disappear. I will tell you why this is important.
Take the classic pass for an example. Now, the pass should usually not be done under spotlight while your hands are being burnt. However, if you do use the pass in these conditions, which will look less suspicious and more natural to someone who should not be suspecting anything: 1- a pass where your hands barely move at all, or 2- a pass with so much hand and arm movement, it looks like you are having a spasm. ??

Your goal as a magician, should make it seem like you are not doing anything out of the ordinary with the cards. If you possessed real magic, you wouldnt have to move all your body parts around like a flailing ADD, drugg-ed up octopus out of water... you would only have to put the card in the middle, snap your fingers, and it would be on top again. Thus, you should do everything in your power to make it look like that is all you are doing.
I think you have a good idea on a progression for your ACR. and honestly, if you spend a solid 6 months working on it to perfection, you will have quite a good table version ACR that you can be prowd of.
Good luck.
