General shift of the nominal AW/BR dimensions (stippled region within the dotted rectangle) to higher values of θ_c (striped region within the solid parallelogram) as the actual dimensions routinely result in smaller wire SIZEs and larger bracket SLOTs than those reported. Note that WIDTHs are not reported on product labels, although they are equally important from the viewpoint of determining accurate BRACKET INDICES. Indeed, the unexpected shifts to the right for the AW/BR couples that involved the 22-mil brackets versus the expected shifts to the left for the AW/BR couples that involved the 18-mil brackets underscore what can happen if incorrect WIDTHs are presumed in the first place.3
