Well, I and Graham are demonstrating how much the increased weight reduces the top speed; increased weight naturally changes the Cl/AoA at top speeds. However, you are demonstrating how much the speed (or power) should be increased to keep Cl/AoA constant.
Basicly you are using the wrong approach for this particular case; we are interested about the speed change due weight change and that also means that the Cl/AoA changes.
