A couple of points. #1. Twin fist had a thread with regard to his frustration about the pattern. It is now clear why he was so frustrated. He followed what all good students should follow, the stipulated parameters. If there is an error in the parmaeter, do you think it improper to find out? (It does not demean his efforts, it does question the standard he was following). #2. Would you consider it an authoritative text about the complete book of the alphabet, all 22 letters? #3. wuld you rather find out you were making an error, even if based on faulty information or would you prefer to commit the error forever and teach it to your students.
I for one think it imortant, for teachers, particularly to be clear in what they are doing. If I make a mistake, as a student, it results in one individual making a mistake. If I make a mistake as an instructor, it can be compounded multiple times.
I have asked General Choi about what I was percieved to be an error in his book, and he was glad to have it brought to his attention. Others did the same. I am glad when my students ask me about what they percieve to be errors. Sometimes it is merely a miscommunication and sometimes Iscrew up.
In this case the pattern has a diagram. 3 Horizontal lines bisected by a vertical line. The moves should follow the pattern diagram lines (more or less) in the verson reportedly contained in He Il Cho's book, the entire top line is missing.
I have tried to find AIMAA pattern video or text on line and was not successful.
