Go back and re-read. My posting speaks to the fact we cannot characterize the affects of weight as insignificant despite the fact we only see a small reduction in velocity at top level speed.
You have invented your own issue.

The point is that you need at least one constant key parameter, and in your calculation you keep Cl/AoA constant. Therefore you also estimate speed reduction to be much higher than it actually is.

Certainly. The reason it is higher is because we do not have the coupled affects to deal with and cloud the issue.
We see the magnitude of the affect of weight in our parametric study.
Why do you think the forumla is there under the portion explaining the affects of weight in the aerodynamic textbooks?
All the best,
