The difference has been noted tens of time above; I calculate the new balance point of drag, thrust, Cl and speed at constant power; all affecting parameters are adjusted to reach new balance and in the end these are in perfect balance. This is the same as real world situation at constant power.
You calculate how much speed had to be increased to keep constant Cl and therefore can't reach the new balance at constant power. This is not the same as real world situation at constant power because there is no more power available and Cl can be adjusted .
Shortly:
Iteration method => all the parameters are adjusted => constant power problem can be solved.
Parametric analyses => at least one fixed key parameter => constant power problem can't be solved.
