NCAA Pitching Lane lines

[Steve M]

OK, after a number of games, I have not seen these lines drawn in the same way at many of the sites I've been to. I have seen these 4-inch lines drawn so that the 4-inch line is split by the end of the pitcher's plate. I have seen these lines drawn so that the inside of the line begins at the outside of the pitcher's plate. I have seen these lines drawn so that the outside of these lines is at the ouside of the pitcher's plate. I'm not seeing any consistency in how these lines are drawn.
From my standpoint, I see the purpose of these lines as preventing F1 from extending the width of the pitcher's plate. If my understanding is correct, the only way these lines should be drawn is with the outside of the line lining up with the outside of the pitcher's plate.
If, however, the purpose of these lines is to limit or prevent the violation being called for being outside these lines, then we can pretty much eliminate the call by having the inside of this lane line lineup with the outside of the pitcher's plate. Now, these site that split the line with the outside of the pitcher's plate just didn't make any sense to me.
