Not much to add after the last three answers. They were all very very good. I would sum up saying you need to pay attention to the scent you are leaving down, the impact on the area you have everytime you enter it. If you start to see deer movement changing then you need to figure out why. Has the food source changed or is it you. Scent control, entering and exits, location of stand (bedding area or feeding area or transition area) ( urban or rural) all these make the biggest factors on how often you can hunt a stand.
