I can 2nd your comment.
I've had zero busts (of severe intensity) from ground odor for several years now.
Yesterday was another example. Had a 1.5 year old buck follow my access trail for at least 50 yards to the base of my tree, at which time he stood there smelling where I'd just taken a leak within 15 min. earlier.
A couple hours later, I had an adult doe standing in the same spot with zero concern that the boogie man was 15 feet above her.
She was under me for many minutes and then she finally worked her way down wind. My milkweed floaters drifted no more than 7 feet directly over her head. I knew it as a matter of time until she got a stronger whiff of me, which she did. But the extent of her alarm was to nervously look around for a few minutes and then just walk away. I guess you could classify that as an odor bust, but it was about as mild a bust as I could hope for.
Last week I had a mature 10 point walk down the same access road as I walked 15 minutes earlier. I wheezed him off of that road and into the cover I was in but he just wouldn't commit enough for a shot. Once again, he showed no awareness that he walked where a human just walked.
I killed a doe last week that was standing exactly where I entered the stand. She was as calm as could be.
I used to worry (and get busted) by deer cutting my trail to the point that it effected where I would even consider setting a stand. Not any more.
Clean body, clean boots, and don't touch anything along the access route and busts are a thing of the past. It's so rewarding when you fool them.
