It is quite some revelation that essence of Maestro is based on flight plan data rather than the use of real-time radar speed and positional data.
That would appear to be the magic ingredient that makes it so wonderful in producing such quizzical and shocked looks across the flight deck when receiving conflicting speed control instructions from sequential control agencies!
I hope we have a copyright on that software so no one else in the world is allowed to use it!
