@Topcon, Scaled accuracy, it's why I posed the question. Although if you placed the line at 3/4 distance from the inner edge would that bring it closer to the track length. ( 30" safer barrier + 13.5' = 16' which is close to a 1/4 of the 60' width ) .  An easy road course would be Brands. Official published data for the indy track is 1.208mi = 1944.0876m
