which rib? Is it Rib 10? i.e. the lowest false rib. So, not the floating ribs? (So, not ribs 11 or 12) (Even though ribs 11 and 12 are lower than rib 10) would anybody consider their statement about lowest rib to be rib 12? (which is technically lower than rib 10) https://corporate.bwfbadminton.com/statutes/ https://extranet.bwf.sport/docs/document-system/81/1466/1470/Section 4.1.4 - Alternative Laws of Badminton - V1.0.pdf " 9.1.6 a) the whole shuttle shall be below the server’s waist at the instant of being hit by the server’s racket. The waist shall be considered to be an imaginary line round the body, level with the lowest part of the server’s bottom rib; b) the shaft and the racket head of the server’s racket at the instant of hitting the shuttle shall be pointing in a downward direction.
