The answer to this is a bit in depth. But inside the game files your True energy vaule is 1.0000, I added code to display this and to increase the vaule to a even 100, The reason 105 maximum Energy does not increase the True energy vaule is because "maximum energy" is really "Energy Reduction", what it does is reduce the energy spent on skills and abilities by -5%, if your "maxium energy" was 110 it would be -10% and so on.
