In a PERFECT world with PERFECT weather and no hunters in the woods it probably could be used. HOWEVER, pressure, weather fronts, etc all effect it. It' s not a given. You don' t get big bucks without having them in the woods. IF they' re in the woods they eat several times in a 24 hour period no matter what. They need fuel. I hunt when ever I can pretty much. The deer are always there. I' m not about to become dependant on the MOON and restrict my hunting to a week a month, because that' s what you' re talking about. A hurricane or the first bad snow will throw your moon deal right out the window. So will hunters walking through your woods the day before you plan to hunt. They may tend to move later or earlier, but there' s only so much daylight to hunt. Change stands daily and don' t come back to one for a week or two and you won' t have any problems. You do your home work and set your stands accordingly, you' ll have your deer before the moon worshippers get in a tree waiting for THE MOON. It' s mostly hype to sell you a moon chart for $25.
