The quantum world is logical and structured. I would think that most if not all structured systems have a large part determined a priori rather than chaoticly formed with retrocausality.
Regarding quantum wave-particle duality; The apparent phenomena observed are part of a structure and field of the entire Universe. I like the quantum super-position questions and sum-over-histories paradigm for interesting thought. To the point though; consider an ocean wave or swell that is an area phenomenon rather than a point phenomenon that it could be taken for if measured at a particular location where its energy is focused or elicited with observation. Maybe it is like that, although just analogously. The strength or location measurement of a wave may be greatest where it is observed.
