Luke, nothing personal to you at all. Apologies if what I said came across that way.  

Several responses to yours and other previous posts could have been interpreted by a casual reader as pushing the boundaries.

I am also particularly sensitive to this type of discussion after sitting through this presentation at the Ukraine meeting on Friday.  

BTW this speaker was from Canada, not the Ukraine.

And as far as pushing my methods over others in my response to him at the meeting, frankly describing my methods was the only concrete factual reply I could think of at the time. I felt that I needed to say 
SOMETHING to respond. He hat lots of data all I had was my personal experience. Should I have said nothing? Jim at Dawn
