I'll have to check that out. But there is no placebo effect. You most definitely do not get the same responsiveness out of lead as you do tungsten.
Tungsten has a density of 0.70 lbs/in3, which means that a cube of tungsten one inch on all sides would weigh 0.70 lbs – 1.74 times more than the same sized cube of lead.
Thats only one part of the equation.
This is then multiplied by this:
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid.
Therefore you have something that is 1.74 times more dense so with the same weight you get a much smaller profile causing a far smaller displacement of water reducing the buoyant upward force on the jig.
So this is the more complicated reason why tungsten is superior to lead and also why you could never fish a 1/52 ounce lead jig but you can actually fish and feel a 1/52nd ounce tungsten jig on the end of the line.
I could care less about fall rates. Fall rate is not why you fish tungsten. You fish tungsten for continuous contact with a very small presentation.
Hey but I'm not the Engineer... RAVYAK (Tyler) where you at. We need your two cents on Tungsten.
