We note in passing that our initial computational experiments with an n-LMF having hyper-meta-GGA input features, where we evaluated the full GMTKN55 suite every 1000 epochs up to 8000 epochs (see Figure in Supporting Information), provided no improvement in WTMAD-2 beyond 2000 epochs, even though the data for the W4-17/BH76 optimization sets still varied. This indicates that the choice of a specific solution on the plateau of Figure for the n-LMF may have only a minor impact on the wider overall quality of the functional.
