live confidence 0.90 39ceb796

The 0.30 kcal/mol target is met only marginally and non-uniformly: the dispersion class (MAE 0.350) exceeds 0.30, and errors grow away from equilibrium - by distance-scale MAE is x0.90 0.344, x0.95 0.306, x1.00 0.268, x1.05 0.236, x1.10 0.207, x1.25 0.236, x1.50 0.386, x2.00 0.343 kcal/mol.
