Better COR is higher or lower

So to answer your question, higher COR is better - a "hotter", more efficient bat. There will never be a 1.0 or higher bat as that would increase the amount of energy in the system and contradict one of Newton's laws of Physics.

It was not Sir Isaac Newton that formulated the equations for the Conservation of Energy. It was Gottfried Wilhelm Leibniz (see Newton vs. Leibniz and the invention of Infinitesimal Calculus; either you are a Newton man or a Leibniz man, ).
