You are exactly right. I should change my first post. Density and viscosity increases which reduces flow and therefore flow would NOT increase at a rate proportional to pressure. Very basic fluid dynamics. However, flow SHOULD increase significantly when pressure is quadrupled with either a laminar flow element or simple orifice.
OK
My limited testing (9.5 bar on the surface) gives something close to the findings of the Pelagian-folks. I believe their finding is an about 1% increase per meter depth.
