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.
For most deer hunting situations in the midwest, yes. In the mountains it can make a much larger difference.
I also think that it is good to have reference points of known distances so you don't have to go through the exercise of ranging every deer. Doing that can be a real problem if it is a buck on the move.
