Target subcooling at 80°F = 11.8°F. Target subcooling at 90°F = 11.9°F. Target subcooling at 100°F = 11.9°F. Target subcooling at 100°F = 12.1°F. You can see that this range (from 11.7°F to 12.1°F) is very tight; only 0.4°F difference between very low 70°F outdoor temperature and very high 110°F outdoor temperature.
