The original inquiry was about returns on cognitive performance. One source of return is the sort of thing you’re talking about here: moving from 99.9999% to 99.999999% accuracy.
A different, but overall much more valuable source of return is increasing the scope of things for which you move from 1% to 99%. It’s much more valuable because for any practically possible level of cognitive capability, there are a lot more things at the low end of predictability than at the high end.
If you want to restrict the discussion only to the first class though, that’s fine.
