I don't mean to insult anyone but there is no need for a pendulem unless you shoot a very slow bow by todays standards.I've used several pendulems on and off over the years and none of then ever got me past about 32 yards.Like was said earlier,if you bend at the waist,you will not hit high.I've shot over 285 fps for several years now and one pin is good to at least 30 yards if I sight the bow in for around 25 yards.I'm now shooting 299 fps and I'm within two inches of where I'm aiming from point blank range out to 32 yards.It's the same at ground level as it is in a tree.If your point of impact is different from a tree than it is from the ground,your form needs work.
