It's only a net 0% if you use no other mods that affect duration or efficiency. When paired with just Streamline, your net energy usage (lower = better) is 0.25 / 0.4 = 62.5%, nominally better than just Streamline's 70%. When paired with just Continuity, it's 0.4 / 0.7 = 57%, better than just Continuity's 77%, and with all three, it's 0.25 / 0.7 = 36%, better than 54% without Fleeting Expertise.
