How exactly do the individual systems scale with the amount of power put into them? I've read that shield regen is zero at 25%, 1x at 50%, 2x at 75%, and 3x 100%, but is that accurate and what about the other systems? Will an energy weapon deal it's base damage at 25% and experience a jump in power from there or is base performance counted at 50% like shield regen was said to be?

And what about the various abilities that scale with Aux?
