Thanks for taking the time out to answer.

That helps to clarify how DT's see themselves and what they do (the 
fact that MR consciously sets a 'mental soft stop' confirms my 
private theory/definitions.

I'm arguing over semantics (to me the words we choose to use,and the 
way we use them, contribute to how we manage ideas) - I concede that 
doesn't suit, or interest everyone.

I'll have a google for Lance Beggs and Mike Reed.

Good trading.
