There are two problems with this line of thinking, though.
Variances vs. New Techniques
- How do you decide what is enough variance of the technique that it becomes something new?
- How do you codify and present the variations? (This may be more of an artificial problem, but we'll get to that in a minute).
This is what I hinted at in my post above. Are the long-range hook and mid-range hook variations of the hook, or separate techniques? Are the lead hook and strong hook variations of the hook, or separate techniques? Right there, you could have 1, 2, 2, or 4 techniques, depending on how you break it down. And different people break it down in different ways.
You can take a lot of techniques and find similarities between them. The front kick and roundhouse kick are pretty darn similar, except that a roundhouse kick includes a pivot that the front kick doesn't. The back kick and spinning hook kick also start off very similar to each other, it's only the final strike that's different. Going the other direction, I know several different wrist locks that we tend to call "wrist lock" but they are fundamentally different from each other in execution. A front snap kick and a front push kick are also very similar (and usually both called "front kick") but executed very different from each other.
You could probably take this to the extreme and just lump every strike under one technique, since physics is the same for every strike. It doesn't matter if it's a knee, a foot, an elbow, a fist, a shoulder, hip, or forehead, the principles of how to generate force don't change from strike to strike.
Where do you draw the line? Where should others draw the line? Is there any particular reason why your line is "right" and theirs is "wrong", other than what you say?
- You want to use as hard of a surface as possible to strike with
- You want to put your weight behind the strike
- You want to accelerate your strike before hitting the target
- You want to follow through after hitting the target
- You want to strike your target on a vital point that's going to inflict maximum pain, damage, or disruption
Codify and Present
One of the issues that I see on a lot of TMA videos is this idea that what isn't presented isn't known. We have one fellow on this site who very much falls into that category (but I'm not going to call him out specifically), where if you don't present every variation of the technique and every way of adapting it, he assumes you don't know it at all.
Now, the simple solution here is just to ignore people like that, but in spite of how stupid the points they're making are, they say them with such conviction that a layman might assume they're right.
Let's say you demonstrate a technique, but you don't demonstrate every variation of the technique. Someone may see that as a hole in your training or curriculum, instead of just something that wasn't included for the sake of time. Of course, now that I think of it, that may happen no matter how you categorize them, as the commenters wouldn't know of your naming convention.
I find it interesting to ask the question: Why? When I look at an art, any art, they have a set of things that they teach and a method to teaching them. So, why do they teach those things, instead of other things? And why do they teach them that way?
Many people look at Karate and go through the Katas to see what Karate teaches. They treat the Katas like a dictionary of techniques that are Karate. That is wrong on many levels. The Kata are pretty terrible as a dictionary of Karate... it does not have all the combinations, all the variations or even all the techniques. Its worse, they list the same technique over and over and over again.
So, why were certain things included? Why were things grouped the way they are? What were they trying to transmit?
Its not a matter of being "right" or "wrong." The different arts are saying different things, in different ways. None of them are saying "Here is a catalog... memorize it." If you consider the total number of techniques that exist and the total number of variations and the total number of combinations and the total number of entries and the total number of finishes... you don't have enough time in your life to do them all, let alone get any repetition. Even if you did them all... how do you apply them?
Each art has a unique view on how to solve the problem. Understanding why they picked a certain set of techniques, why they grouped them the way they did... can go a long way to helping you understand what you are supposed to be learning from it. Yes, memorization has its place... its the very first step. Once it is memorized, and you don't have to think about what comes next.... you can now start to study it. Whether it is a 50 step kata / form or 4 step grap, lock, takedown, finish or a one step hip throw. There are reasons why Karate teaches 50 step katas and Judo teaches 1 step techniques. You can learn a lot be figuring out what those reasons are.
