Ahaa - I get to learn something new everyday! LOL

Sphelps, 4m and 4000l/h @ 85w still sounds to good to be true as that 3-4X the efficiency of the Reeflo
I'm not sure about this - unless the Barracuda operates differently from other pumps, the ability to restrict the outlet does reduce flow, but that isn't linked to power draw - reducing the output/flow typically increases the back pressure on a pump but I'm not sure that it reduces power useage.
