IMO, the best form design is the
- 1st move can be used to set up the 2nd move.
- 2nd move can be used to set up the 3rd move.
- ...
- n-1th can be used to set up the nth move.
For example,
1. roundhouse kick,
2. side kick,
3. spin back fist,
4. hook punch,
5. back fist,
6. uppercut,
7. ...
This way when you train your form, you also train how your opponent may counter you, and how to counter your opponent's counter.
It sounds to me like what you're describing is just a continuously flowing combination. I don't really see how that can be used to set up counters and counter-counters, because as soon as a counter is attempted, it will change the flow of your form.
It's like if you have a river you want to divert, so you plan to put levees and dams at two locations on the river. Once the first levee is built, the river diverts off course, and the site where you planned your next dam is going to dry up anyway. So if you start with roundhouse kick and I grab your leg, a side-kick isn't going to work in the flow. If you attempt a hook punch and I do an outward block, a backfist will be going the other way. If I slip the punch and do an inward trap, you're not going to have the angle to backfist.
I'm not saying it's a bad idea for a form, but I don't think that's the application you could get from a constant stream of offensive techniques.
The form you specify is also devoid of defensive moves. I feel this is important because if you're doing a flow of techniques, how you flow from a block to a strike can be very important. Whether you're talking Taekwondo where you will block with one hand and strike with the other, or something else where you will intercept an attack and follow through to strike your opponent, the flow of defense-to-offense is just as important as one-two combinations.
Now, as to Taekwondo, the forms we do at my school typically have subsets where one move flows into the next, but we also kind of have stops in the middle. So our pattern might be 1-2-3-4, turn, 1-2-3-4, turn, 1-2-3-4-5-6-7, kiyhap and pause. Turn, 1-2-3-4...etc. The form I designed for our demonstration team makes significant use of this, where one technique will flow to the other.
For example, double-knife-hand block, side kick, elbow strike. When you side kick, your hand slides out and extends with your leg, and then when you land, you "grab the head" and elbow strike into your open hand. I took great care in setting it up that as you do technique 1, you are chambering or close to chambering for technique 2, and so on. There's even points where the ending move for a set is basically the chamber for the first move of the next set.
