Lolwut. Vast majority of bearing drag is in the seals, and sealing of cartridge bearings is often sub par. Also, I've almost never seen a cartridge hub with preload adjustment, so no preload is probably a tiny bit less drag.
Give me sealing and preload any day, adjust them properly and never revisit them.
Factor in throwing away your bearings every time they get contaminated, probably not so efficient in the big picture.
Also, hub bearing drag is a trivial factor, given the tyre's leverage over the bearings.
