Really not sure where you are going here, Tom, or what the big picture is that you are asking. Your formulas will work for investment, perhaps, but are not easily captured by most medical, educational or therapeutic models, where the "unit" cost of each incremental benefit may not be known (case in point - is there ANY value in cutting stuttering rate from 40 to 30% of words, and can we make it comparable to a decrease from 10% to zero?) I am still not sure what the point is about validity of post-therapy speech done when the client knows who the listener is, as opposed to anonymously. As researchers, we often feel that this can make results look better than they might, but surely the speaker would know the answer. Am I missing something? if so, please try to clarify what you are asking us to comment on or answer. Nan
