That logic presumes that the first 40 hours aren't affected by the additional hours. IIRC, one of the premises of the "sustainable pace" rule for Extreme Programming was that people know when they are being pushed to work a lot of hours and either consciously or unconsciously slow down at the outset (with the mind or body shifting out of a sprint-mode and into a marathon-mode).
