My DS8 has the asynchronous, wrong tool for the job seemingly due to an early limitation sort of thing (in particular for him a vision limit) where he taught himself whole words patterns rather than decoding. That mode seems to have a direct impact on writing, too. Whether this is long-term diagnosable as a "and that's the way it is" sort of thing (i.e. dyslexia or dysgraphia) or a phase he needs to break-through we don't know yet.
There are brain development aspects that if they miss critical development periods become significantly more difficult later. But when a HG+ kid basically lives in a world of epic paradigm shifts, you kinda get caught up waiting for the one secret thing to click and tada.
