The remnants of temporary lane markings, along with the repairs, mean one cannot differentiate between the actual lane lines and the old removed markings.

Lane lines, starting blocks, even the pool itself all have undergone significant improvements over the years, always with an eye toward faster times.

This usually involves inputting known measurements such as the distance between lane lines or the height of the camera above the roadway.

Mondo surfaces differ in that they are more of a rubber carpet, cut to size then tightly seamed together (in the linear direction along the lane lines).
