The calculated protein-water entropy of the first hydration site for the TIP4P-2005 (magenta) and TIP5P-Ewald (cyan) models using different levels of sampling from the 2,000,000 configurations. For the eight points plotted for each water model 10,000, 20,000, 50,000, 100,000, 200,000, 500,000, 1,000,000, and 2,000,000 samples were taken.
