I think your expectations are out of line ... very few of us would make the cover or an article in a magazine, that is just reality. Stop reading those mags and watching deer TV shows and you will be less frustrated. I probably walk 10 miles for every shed I have found, finding a half dozen 130"-150" caliber sheds in my food plot has never happened.
For your size property, being that is flat, you need screening (hinge cutting, selective harvests, & pine/scrub plantings). I would stop focusing on holding deer and create structure that encourage deer to use your property as a travel corridor. If you want to focus on holding deer, focus on does. Transitional food plots could also help. That way the bucks will have the safety of cover to scent check your property for does bedding and can use your property as a transition area.
