Long time since I worked at Willy - but looking ta the map now - the Control Zone is actually 12nm.
The airspace outside that (to 25nm - see below) is part of the restricted airspace associated with the Willy training areas.
I don't know what airspace Willy activates on weekends to process aircraft, but I can't imagine its all of the CTR (SFC-5000), R578A (5000-FL125) and R578B (SFC-FL125) is it?
