I watched as a hunter using a Matthews compound producing 287fps missed a blacktailed deer, that dropped under the arrow at 12 yards. The hunter is an excellent shot and hunter and that danged deer dropped under the arrow that would have otherwise double lunged the animal. He was on the ground in a natural blind for cover. The deer was nervous and his ears focused on the hunter who was already at full draw. When he released, the deers reaction was instantaneous. The bucks body literally hit the ground and spun before the arrow struck the tree ten yards past it. I didn't read the article in Petersens, but seems the author needs to do a little more research and try that one again.
