Ranks don't always equate with experience, especially when you compare across styles. Which class was so "traditional" that nobody spoke during the class? I know a fair number of people in some very traditional styles, and they do speak. I know a few cases where there's little speaking because the instructor doesn't speak English... and a few others where there's not much speaking because nobody's got the breath left to speak. I'll ask you what I'm pretty sure I asked Mr. Case: What is "matrixing?" How does it help learn?
