I also hunt NH as some other NH hunters here have stated. I am lucky if I see deer 3-4 of the 7 days I hunt. Sometimes I can go an entire week and not see a deer, other times, I see deer almost every day. Plus I hunt all day, every day, dark 'til dark.
Constantly moving has increased my deer sightings. If I see no deer or reason to stay on stand after 3 sits, I will move. This has been my approach only for the last few years. I can be and was a stubborn hunter and overhunted my stand too much. I thought, the longer I stay in one treestand, the better my odds the following day. That definitely is not always the case.
