A Monte Carlo model predicts that a three-grating neutron moiré interferometer with a one-ton lead mass can measure G to 150 ppm, and reanalysis suggests lunar tides may add tens of ppm to some prior torsion pendulum results.
This uncertainty in the grating period, using the Monte Carlo simulation, leads to an uncertainty in G of 57.7 ppm

Design and Monte Carlo Simulation of a Phase Grating Moir\'e Neutron Interferometer to Measure the Gravitational Constant
A Monte Carlo model predicts that a three-grating neutron moiré interferometer with a one-ton lead mass can measure G to 150 ppm, and reanalysis suggests lunar tides may add tens of ppm to some prior torsion pendulum results.
