dethhead,
I commend your enthusiasm, but whoa...slow down.
You simply cannot learn a kata by the list of techniques. What about all the other stuff that goes into a kata...the stances, the directions, the tempo, the breathing, the rhythms, the bunkai...
If you just memorize a list of movements, you are wasting your time and may as well be in an aerobics class, because what you are doing is not karate.
Yantsu is a fabulous kata. It is one my favourites to perform in competition, even tho it is a low-kyu kata, because of the eplosive power you can generate with well-executed hand movements.
A very useful rule for your karate training is....learn it right the first time. And at the risk of sounding like a walking cliche, remember "only perfect practice makes perfect".
So, I agree completely with jap-man. Go back to your instructor, and ask to go through it again...and again...and again. Don't risk embedding the wrong thing. As an instructor, there are few things more frustrating than a student who has rushed ahead and taught themselves the wrong things.
If you can only work on it for 10 minutes at a time, then do 3 movements PERFECTLY, instead of 20 movements, poorly executed, adn poorly remembered. You have the rest of you life to enjoy the beauty of this kata when it is perfected. There is no rush.
