From the curve, looks like a 60% antifreeze and 40% water mixture is significantly better than a 50/50 mix....wonder why we all do 50/50?  Corrosion protection should also be better with more antifreeze...just thinking.

Coolant is cheap.  Engines are expensive.  Drain some of your mix and add pure coolant until you are satisfied with the protection level.
