Hi,
for myself I found the following "guidelines" (which apply to my studies I do alone, in the dojo it's a little different though):
- I repeat Kihon first, before I actually start with a new Kata. It might seem obvious, but I mean: I really take the time to re-read, re-think and (most important) re-do [isn't it funny that the english word "do" (doing, making, building) and the japanese word "do" (way, path, exercise) are so similar?] the basic steps. Very slowly (like in Tai Chi) I try to check the movement, the stances, the positions of arms, legs, hands... Without any power I watch my body move and adjust certain things. So I want to avoid my body to get used to wrong or sensless movements.
- I study the books and watch vidoes, but not the whole Kata. I break it down into parts, depending on the length of the Kata. It does not make sense to me to learn a kata all at once. E.g. when I studied Wing Chun it took me half a year to learn the first kata. Before that I had to repeat pieces of the kata over and over again. I think this is a good practice, therefore I stick to it.
I do this very slowly again! - I pick certain, special parts of what I've learned so far and take a closer look at these spots. E.g.: in Jion there are several spots where you have to do "Manji Uke". I realized that the position of my rear arm (the hooked one behind my head) has a slightly awkward position. So I studied switching sides in Manji Uke in front of a mirror.
- When I think I know these parts of the kata, I start doing them faster with more power. At this point I keep asking and showing the Kata to my sensei.
- When I have all the parts together I do the whole kata. First very slowly (Tai Chi again), then a litle faster to have the right rhythm/timing and feeling for the imaginary horde of opponents. At last I'll try to do it with "full power" (to please the jugdes ).
At this point I can say I know the basic steps of the kata, as well as the timing. But this does not mean I really "know" the kata. As we all know, it takes a very long time to really get a kata into ones mind and body. I use this guidelines also when I study bunkai/real application of any techniques/movements and it takes a long time to have the body "reacting" without "thinking" correct.
Generally I don't think it's good to know 26 Katas. I don't see the point of if, really. Especially when I see my younger comrades in the dojo, wearing green or blue belts and studying Bassai Dai and Jion for tournament, I get a little sad. Their techniques are not neat/clean. They do just a dance...
I maybe a Troll, but that's the way I see it.
