When you are up a tree you dont have to resight just bend at the waist.
You can tune your bow so the field points and broadheads impact in the same spot if not you will have to resight broad heads.
The muzzy practice blades shoot exactly as the razors do.
The best thing you can do is practice not only on the ground but from up a tree at your hunting height just remember to BEND AT THE WAIST.
Also practice sitting kneeling and in every position you can think of.
Did I mention that when shooting out of a tree to bend at the waist.

Hope this helps.
