That stuff is BS in my personal experience and opinion.
I hardly ever range objects from my stand. I NEVER range from the ground. I just range the deer before I shoot.
If my rangefinder reads 40yards, I hold my 40yard pin dead on where I want my arrow to hit.
That's because the difference is VERY LITTLE,on relatively flat ground,especially as you get further from the base of the tree.
BUT,if you are in a stand on the side of a hill that is 40 feet high+ the stand height,then you might not want to shoot for what the rangfinder says,you will most likely miss.
So,it isn't bs,it is misrepresented at times and greatly misunderstood,but not bs.
