I will say this for the thing, it does make you think every day. You make the decision to actually go to the gym or loose a point on the scheduled days. You make the decision to grab that fast food or get something better at home. I adds a little bit more accountability, though not 100%. You can still schedule too many exceptions, which is something that I ended up doing this month.
I can certainly see where it would seem like a lot of work though. From my old exercise diary, I was pretty much in the habit of writing stuff done each day. That was a huge help.
