You don't distinguish your facts from your inferences well enough. Your list of "facts" seems to contains inferences like "Therefore time turners were limited after the invention of Equinoctal hours, in 127CE.", speculations like "Wizards seem to spend most of their time in pocket universes, otherwise you'd spot dragons and hogwarts trains on satellite imagery." and assumptions like "Children have unconscious magic, but not to the extent that OT Harry did."
