edits to three techniques to incorporate survey comments

I have made edits to three techniques (noted by my name in wiki) to 
incorporate (minor)
survey responses.   Please check to see if you agree with my edits; also, I 
wasn't sure where to put some edits requested,
and I have some NOTEs in the text indicating questions I had.

Thanks and best wishes
