It’s of course possible that this is because the methods are bad, though my guess is that at the 99% standard this is reflecting non-sparsity / messiness in the territory (and so isn’t going to go away with better methods).
I have the opposite expectation there; I think it’s just that current methods are pretty primitive.

I also think current methods are mostly focused on linear interp. But what if it just ain’t linear.
