The operative word being "goal", something to aspire to, rather than an absolute.

My "goal" is to kill things with one shot and it is achieved better than 90% of the time, so I'd give myself an "A" in that column. However, killing game from a solid rest in a cut corn or bean field is usually pretty easy, really more an exercise in preparation and "shooting" skill rather than "hunting" skill. Plus, all of my hunting is done on private land where there is no hunting pressure and in a State that allows each hunter to purchase two antlered deer tags and, in some of the GMUs where I hunt, as many antlerless deer tags as a hunter wishes to purchase. I only shoot two kinds of antlered deer, trophies and culls. I don't shoot bucks with little racks, unless the antlers are damaged and there appears to be a genetic flaw that should be removed for the good of the herd. Because of that philosophy, I only punch my antlered deer tags about half the time, maybe even a little less than 50%.
