Okay, here's a graphic I made in response to a PM asking how adding a CoF would sharpen the curve, and make "skilled" players more remarkable.
If we look at this, and notice the "non-COF" impacts. They all hit the CT, even if the "moderately" skilled players is all over the place. Now when you look at the possible impact zones (meaning the shot could land anywhere within that area) you will see that the highly skilled player is still hitting the CT the MAJORITY of the time, with some spread to the L/R torso and maybe even to the arms and legs in extreme cases. Meanwhile, the moderate skill side shows that those shots that would have ALL hit the CT before are pretty evenly spread across the three torso sections, with a good number of them hitting the arms and legs (maybe even a few misses).
This is what I mean by sharpening the curve. This is why in
real-life marksmanship, you always aim for the same point in the center of the black, rather than any point in the black. The difference between an expert shot and a good shot, is how consistently they place their sights on the exact same point on the target.
