Walls, fault lines and targets are placed from the dimensions on the classifier sheet. Sight lines follow the rulebook: walls go from the ground to infinity, hard cover and no-shoots are impenetrable, and the feet stay inside the fault lines while the gun may lean about a foot past them. Route times come from a shooter model with a draw, splits, transitions by swing angle, movement by distance, and aim time traded against expected points, calibrated so the Grand Master profile lands near the official high hit factor.
