J46: i can understand the DD generalizations. There are a number of us that post sporadically. Does this mean we've done less or more than anyone else. I don't think so. The fact is a number of high profile posters made, with genuine intentions, incorrect assumptions / conclusions for whatever reason at times. This is an exchange board and that's what happens. You state some dd you've done. it Sounds great but what does it really tell us.
I read certain posters (yours too) to gain their insights and then add/subtract in formulating my own opinions - I rely in myself. Doesn't mean those like me, rely on the five noted.
