At least they are giving you guys a heads up and when desiging a pit display you should have a plan to trim it down a foot or two! To an extent you can't really plan things out 100% when it comes to the floor plan of an event when you need to consider traffic patterns and major intersections where extra space will be needed for safety.
A 10x10 pit is not guarunteed when competiting. They might have to sqeeze 6inches or maybe a whole foot but just live with it and enjoy the Championship!
