You're right about it being linear, but the wasted power figure is a bit off. The BEC has to dissipate the differential voltage times the current. So, for a BEC value of 6v and 3s lipo (11.1v) and 3A load, the wasted power would be 15.3w. Either way, on anything over 2s and 1A load, they are too inefficient. Which is why I recommed a UBEC on anything above 2s lipo or 7 NiMH cells.
