It depends on the species...and as you know there is a wide variety over there. The big animals don't move much. Kudu, Eland, Wildebeast, Zebra, Waterbuck..etc, with the exception of kudu cows. Most are not going to move much at your shot. The smaller animals are a whole new game, with the worst being impala in my opinion. But don't get too caught up in it. Compound guys have more of a problem with it than guys shooting recurves and longbows. I had a guide on my first trip over there that swore up and down that Impala are so jumpy...that I needed to aim at the first joint on the front leg (from the hoof up) and that the animal would drop right into it. Well, I had a beautiful ram at 20 yards. I aimed at that first joint..and guess where I hit him? Right where I was aiming? The reason is that most of the time..you will be hunting out of an enclosed pit blind. Sound does not travel very well out of them. You have probably noticed this if you have seen videos of people talking to each other with game animals under 20 yards away that are oblivious. Since then, what has worked for me on the smaller species is this. First of all...no matter how tempting...do not shoot until they are actually drinking. They are nervous as hell approaching the water...but once they begin to drink they calm down alot. On the smaller animals...I aim straight up the front leg, and less than a third of the way up the body. Think heart shot. This has served me well on impala, bushbuck, and even a mountain reedbuck. On the big stuff, that I previously mentioned...aim where you want to hit them. The big ones pretty much just stand there and take it. DO NOT underestimate the ability of a warthog to jump the string. I have video footage of 5 warthogs I shot over there, and every single one of them moved when the bow went off, whether they were drinking or not. If they are drinking, they won't move too much, but they will move. This for sure is another animal that you should wait till they are drinking before you shoot. As a side note about the waiting till they were drinking thing...last September, I had a nice impala ram come in alone. It was a wet year, and while he came in near the water he did not act like he was really interested in drinking. He was only 15 yards so I aimed at the bottom of his belly line and he dropped right into the arrow and got it in both lungs. In this case...I simply did not feel confident that he would drink, but due to the short range, I did feel confident in the shot.
