Hi Fred,
Another Ron here. Clark Sprague came up with this slick little calculator a 
couple of years ago when we were discussing this.

Where Speak is speaking length, and Target is where you think you want the 
duplex length:

Partial=INT((-1+(1+4*((Speak^2)/(Target^2)))^0.5+1)/2)

Duplex=Speak*(1/((Partial)*(Partial+1)))^0.5

I think that's right.
