My question is :
Fist of all, we need to measure the divergence between actual hours spent and SNLT. How can you know  that divergences will roughly cancel out without measuring the divergences itself? It looks not so much an explanation as a presupposition to me. Answering Jerry's question in the way above is guilty of circular reasoning, I think.
