Graham's original point:

"Actually, fuel state is not that important with regard to maximum speed."

Is in the first page and posted before you entered to this discussion. And at page 3 of this thread you state that:

"My issue has always been that Graham's original post:"

and then you quote that same part which Graham posted before you appeared.

What they do not account for is the magnitude of the affect of weight.

It's all there, the changed Cl, Changed D, Changed T and changed V. All at new balance point due to increased weight.

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.
