What is key is that bowlers [I]accept[I] the fact that topography does affect the lanes as much as, if not more than, oil pattern. The analogy that I used in the last BTM article that I wrote was that of Black Holes. Astronomers know that black holes exist despite the fact that they can't see them. They know because they observe the motion of the stars around the black hole. Bowlers can easily see the topography by noticing the motion of their bowling balls as they travel down the lane surface.
Now topography doesn't change (noticeably) over the course of a series, But a oil pattern can change drastically over the course of a series. While the topography doesn't change over the course of a series, how much it affects the ball does change as the oil changes. When a particular topological feature is covered with oil, the ball will be sliding over it, minimizing it's effect on the motion of the ball. As the oil dries up, friction increases, letting the topography rear it's ugly head. When the feature is negative (angling away from the pocket), the ball will appear to slide further, causing many bowlers to start talking about carry down. It's not carry down, it is simply the emergency of negative topography in the friction.
