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.
If you are 18 feet up in a tree,and you range your deer at 40 yds, that means it is 39.55 yds from the base of your tree....OF COURSE your 40 yd pin is going to work. Nobody ever said it wouldn't.
