A method of decreasing the operational stresses acting on a target airfoil row in a turbine engine; wherein the target airfoil row is bordered on each side by a first upstream airfoil row and a first downstream airfoil row; the first upstream airfoil row and the first downstream airfoil row having substantially the same number of similar airfoils and both comprising one of a row of rotor blades and a row of stator blades, and the target airfoil row comprising the other; the method comprising the step of: configuring the circumferential position of the airfoils of the first upstream airfoil row and the airfoils of first downstream airfoil row such that at least a portion of the airfoils of the first upstream airfoil row and at least a portion of the airfoils of the first downstream airfoil row comprise a clocking relationship of between 25% and 75% pitch.
