The paper defends the inverse-problem view of LaMET reconstructions and argues that rigid parametric extrapolations underestimate PDF uncertainties when lattice data are noisy.
The lattice data should be truncated at a point within the sub-asymptotic region where they have decreased smoothly to near zero
