Although it can still be deeper while being memorization. For example:
1. Memorize the basic steps and moves
2. Memorize each chamber position
3. Memorize each stance and the details of the stance (i.e. how far apart your feet are in X and Z, where each foot points, etc).
4. Memorize the timing of each combination
5. Memorize the breathing pattern of the form
You can memorize more and more details. The way I put it is that at the white & yellow belt level, there might be 5 details for each technique (3 details for stance, 2 details for the execution of the technique). But at my level, there are over 30 details for each technique in a form. This includes every major joint in both the chamber and completed position of the technique, as well as the path of travel in between.
Getting all these details right takes a lot more than a few days.
In my opinion.... step one is memorization. It does not matter how much you memorize, if all you are doing is memorizing more things, that is still step one.
Step two is going beyond memorizing. Why? Why am I in this position, when doing this technique? Why am I transitioning to the next stance and the next position? What is happening? As I make these movements, in these stances, what is happening in my body? What are the real world applications of these movements? Why are these moves grouped together? Why are they in this order?
Most arts have some form of step forward, lunge punch. Your right foot starts out behind, with you right hand in chamber. You step forward with your right foot and throw a straight right punch, leaving you in a forward stance, right foot and right fist forward. Step one is memorizing all the details, all the angles, all the positions.... Step two: why are you stepping forward when you punch? What is accomplished by that step? What can it help you to learn and practice? What can you take from that forward step, and apply elsewhere.... even to things that are not a punch?
The step forward in the lunge punch, teaches you to make an explosive forward step, it covers a lot of ground, it teaches to to end your forward motion on balance without over extending, it teaches you to use your feet to maximize reach without sacrificing your posture, it teaches you body unification, it shows you how to use your legs driving into the ground to add power to your strike, it shows how transferring your weight generates power and how to connect the leg power, the upper body power and the power generated by transferring your weight... (and a lot more) How can you use those things in other areas? Why does the lunge punch come after the down block in the kata? Why does it come before the next technique?
Then, look at why those moves are in that order together. If you think of a kata / form as a paragraph... what is the point of that paragraph? What is it saying and what can you learn from it? Why do students study this paragraph first before this other paragraph? What does the first kata you learn have to do with the next kata?
None of these questions I am asking, are answered by memorizing the angle of the bend in my elbow. These are the things you can focus on, once you no longer have to focus on what are all the angles of all of my joints, what is the next stance, what is the next technique...
The only reason for memorization, is to free your mind up to focus on what is really important.
