That doe Will remeber where she saw you. therwise if there are a ton more than just those 5 ye your done, otherwise you should be fine if it continues to happen I would deffiantly move my stand to a tree wiht better cover and you dont have to be 20-30 ft either I have stands as low as 6 ft becasue there is a perfect group of pines pr hemolocks that wont cover me past that hight and see deer. or try a ground blind,
I have had a ton of deer stand 10-15 ft away and Not have a care in the world with out any extra structure other than next to a dead fall or under a hemlock I have even just set it up on a ridge and had them look right at me and keep eating. The one thing I did Notice was that after they eat an acorn they'd look up at every tree !!!!! I personally see more in a blind un less I find a good tree with hemlocks or pines covering it.
Good Luck and let me know how you make out
