Some events use more than one last control. The distances from these last controls and/or the types of marking may differ.
The type of marking is controlled by a setting in the control dialog for the finish point.
As long as the type of marking is the same from all last controls, you need only one finish point. The distance from the last control will be calculated automatically for each course.
However, in the unusual case, where the types of marking differ for the last controls, you need to create two finish points on top of each other; one for each different type of marking from the last control. Assign the correct finish point to each course, depending on the type of marking that is relevant for the course.
