I'm not a Q researcher just an observer of mass conscious trends and someone who has been aware of the corruption for years so I'm sure people here have great examples of actual drops. My theory is more big picture.
If Q is a Quantum computer than multiple (infinite) timelines exist and would be able to explore infinite possibilities and determine the most likely occurence. In fact there are probably infinite other timelines where Trump ran against Obama in 2012 and the plan already played out. Using these alternative timelines Q can put together with near certainty the events that will unfold in our own timeline.
