Now we can all agree that with severe overweighting you need to fill your BC up a fair bit, increasing the surface area that is exposed to the water at a greater than ideal angle, creating more drag. More drag = increased force exerted by the water on you.

Where does the increased angle come from?
With my jacket BC the extra area/volume is under my armpits.
With my wing the shape becomes more streamlined.
