XD aliens operate in the following way:
They observe one quantum, among two. They then say there must be this one quantum, it has been observed. They do not take their eye off of it. Then they add another quantum in the group, and are unsure which one they have viewed, but know they have viewed one.
They then can choose between two quantums and decide which one they want to have faith in that they have observed, and it is. This is the #11. 10 being reality, one steady complete vibration, and the 11 being one higher, the pair of quantums.
Effect Z upon them.
