Sorry, guys, I'm not a mathematician by a long shot so the numbers don't do much for me. What I see in this article is an egghead telling us that shots where the cue ball and object ball are close together, or if the object ball is close to the pocket are the easiest shots. Then, if I'm not mistaken, he's saying that from the middle of the table, with some distance between the OB and the CB, that any errors will be magnified over the distance to the pocket. Sorry, I thought that was pretty much common knowledge amongst pool players.
