You said it's untrue that you can predict a typical coin flip because it's a chaotic system. I laid out the limitations of chaotic systems and argued they don't apply to a typical coin flip. Are you arguing about predicting "essentially perfectly?" I use that to mean predicting with a couple nines of accuracy.
By quantum weirdness scale, I mean that the accuracy (epsilon) of a necessary measurement includes accurate position and momentum measurements. If epsilon is too small, we might not be able to hypothetically measure both to the necessary precision. I'm guessing that the necessary epsilon for essentially perfect prediction is large enough that you can hypothetically measure both to within that precision.
