I didn't measure the wire size on the (62mm) . It doesn't matter anyway. Percentage of breaking strength doesn't change with wire siz. Only speaking length. My 5'4" piano had a speaking length of 58 mm. The wire size was .030. Changing the wire size made no change in the breaking percentage. It remained at 83 percent. I can only assume that the 62mm note would exceed that. If you increase the diameter of the wire it must be at a higher tension to reach pitch, hence no change in the percentage of breaking strength.
