Jim,
Perhaps we are talking about two different techniques?  I measure the 
distance from  the back of the moulding of one hammer resting against the 
string to the back of the mouldings of the two adjacent hammers resting 
against the hammer rail. I don't set the let off distance this way because it 
would be harder than setting it the usual way.
No quarrel just learning :-)
