Just like to add my tupence worth. I have been traing in karate for over thirty years now and have seen bad katas and good katas and also some really terrible shodan grades. What is considered good in 1 club may not be considered good in an other,so how anyone can judge a person on the 1 clip is beyond me. If you are a judge at kata then you base the marks on the 1st kata that is performed,either it is worse or better and you mark accordingly. So, please show a little respect for your fellow practioners,you might be that person who goes to a club whose students are better than you and then you might be the one on the recieving end of the laughter. In my opion you are only as good as you think you are,there is always someone better waiting in the wings to take your place but hopefully they will have the respect and tact that some members in here are severly lacking. Regards
