This is not a stupid thread (at least from the begining). I was asking a question to help understand and trouble shoot the matter. As you can see other people are puzzled by the remark in the TSRM. So it was just to understand it.
But regarding the "wrong and contradictory" remark I was referrering to JetJock who obviously could explain the issue but seems to like the fact that he knows and we don't and sort of wants to keep it that way. I think he thinks it makes him seem smarter if he can explain something in a way that nobody understands it. In my world a teacher who understands what the student's problem is and can elaborate on his answer, is always a smarter teacher to me.
