Your measured weight is never constant. There are always fluctuations with everything.
No. Not really. My scale reads completely accurate and consistent to the pound.
Note added. Even more for scales certified and calibrated for commerce. Also for load and weight limit safety. Or scales used to count parts by weight so more useless lies and deflection by you.
Which has nothing to do with den pressure delusion cannot explain.
One, how it can produce a constant “transmission” to foundation when gas molecules move in random directions as seen in a gas bottle. Especially in a chaotic atmosphere where updrafts and thermals are created. In the context my weight is stable to the pond on a scale, and things like updrafts should have great impacts on my weight if DPD was responsible for weight. Gravity and the action of gravity on my mass explains how my scale produces reliable, accurate, reproducible, and consistent results to the pound despite different atmospheric conditions.
Two. You butchered buoyancy which is related to three.
Three. If you weigh objects in a chamber with the atmosphere evacuated. As the chamber pressure is reduced increasingly below atmospheric, objects will weigh increasing more as the effect of buoyancy is reduced. A closed air filled plastic bottle gains a significant amount of weight as the effects of buoyancy is removed. The opposite effect dictated by DPD where less pressure should cause less weight.
Four

DPD has no explanation why a twenty times more dense steel ball falls at the same rate as a ping pong ball. When in DPD the steel ball should be falling twenty times faster. Where in reality they accelerate at the same rate. With history showing gravity is the dominate determination of acceleration. With no correlation between rates objects drop and their densities. And gravity correctly models drag and buoyancy. Not DPD
And you have not provided any model when their densities should change their rates of acceleration. And by how much. And you have not shown, Mr experience, by documented experiment your false assertions are true.
Five. As pressure is reduced increasingly below atmospheric pressure, and feather falls faster and faster. A feather will fall increasingly faster until enough atmosphere is evacuated to the point air resistance is negligible where a coin, a feather, and a bowling bowl will all drop at the same rate. In DPD, as atmosphere is removed things should fall slower. Not faster.
Six.
In DPD where you think molecules expand, there is no free space, and air resistance can never be made negligible because you think your expanded mater is taking up all free space. Your expanding molecules would make it impossible for a carburetor to pick up gasoline in the incoming air via the Venturi for mixing to the right ratio for combustion. Your expanding “gobstoppers” using expanding mater would fill all the free space in the Venturi with mater. So. In DPD there would be no low pressure created by the Venturi. You stated in DPD molecules expand so air resistance is never negligible. By molecules filling all available free space with mater. In DPD there would be simply no room to pickup the gasoline because a molecule of gas and a molecule of air cannot take up the same space.
Demonstrable reality shows air resistance can be made negligible. A feather and a coin can drop at the same rate as enough atmosphere is evacuated from a chamber. Contradicting DPD, a feather will fall faster as pressure is reduced below atmosphere. Contradicting DPD, items will weigh more as pressure is reduced below atmosphere. Expanding molecules with all free space taken with their mater would make the operation of a carburetor impossible as there needs to be free space between molecules to create a low pressure in the Venturi, room to pick up gasoline, and room to mix air a gas to the proper ratio for combustion. DPD has failed to show a correlation between densities and drop rates. While willfully misrepresenting buoyancy.And there still no evidence your atmosphere pushes things constantly to “foundation”

By the way gravity pulled the ball through the atmosphere. Creating drag and low pressure behind it. Showing the chaotic nature of atmosphere as the falling ball leaves a spiraling wake behind it. With no indication the atmosphere pushed down from low pressure to high pressure to convey the ball down.
