This is inaccurate, determinism does NOT imply superdeterminism. Even if my decisions are predetermined, that does not mean that the Bell Inequality will be violated by my choices of measurement settings - which is the premise of superdeterminism.A fundamental theory that is deterministic is necessary superdeterministic. A deterministic theory at a fundamental level allowing "independent decisions of experimenters" is logically contradictory, therefore it makes no sense to seriously speak about it.
Your superdeterminism is supposed to explain something, and it doesn't. Every particle would need to have all the details of all other particles contained locally to work. We have previously discussed this point in other threads, and concluded that superdeterminism has baggage. Further debate of superdeterminism here would be off-topic.
