Should you sometimes practice shooting from a elevated position. I've heard pepole say that it's a lot differnet when your shooting in the air.
If your going to be hunting from an elevated stand then by all means you should be practising from it as well.Shooting down on a target or animal is different from a raised platform then on the ground.From the raised platform you must bend at the waist and aim where you want to hit.Another big factor from elevated stands is the distance looks farther away.For example 20 yards looks to be 30 yards,take some time to get used to this.Remember you are measuring from the base of the tree and not from your platform.
