I think it will worj at just that right time. Thats why it's mixed, and I've had a couple good results from it. Once just like the guy above, I had one cut right towards me grunting heavily. I let him get 5yds before I shot and he never noticed me where he was so focused on the smell. He was following the trail I had walked dragging pee pads. So it will work, you just never know when. Just another way to try to stack the odds in your favor.
