I don't even know what "exceed" means, I couldn't possibly have claimed that
The simulation depends very much on how well the physical dimensions of the drivers involved have been measured.
Any non-ideal behavior of a driver in reality (cone or surround resonances,...) will not be captured by the simulation.
If it turns out well, the simulation of the frequency responses (hor and ver +-180°) is in the range 200-9000Hz at +-1dB (compared to reality).
This means that the simulation shown by Rick should be very close to reality.
Here as large images (normalized to on-axis response):

But that reality outperforms the simulation will rather not be the case. But if the final result comes close to the simulation, then it is better than the majority of Amir's tested speakers in terms of directivity.
