What you are saying is that the two-dimensional method was 

 modified to account for a spanwise variation. An unsteady three- 

 dimensional theory from the outset was never applied. Is that right ?

The lift slope and aerodynamic center modifications were de- 

 rived from steady lifting -surface theory. The remainder of the loading 

 was a fully unsteady formulation.
