Pacquiao's Height?

He is normaly listed 5'61/2" but show time had him listed at 5'51/2".... Did they measure him and find that he was shorter than he claimed?... Also whenever i see a thing with him standing next to roach they look the same hieght and roach was 5'5".... The networks(HBO Sowtime etc.) should measure the fighters so we get acurate and real tale of the tape stats... Seems like allot of fighters lie about their hieght: Tyson definatly didnt seem like he was five eleven and a half... and ray loenard admited to being five nine not five ten.... also marvin hagler when he faught duran looked like he was the same height as him. im not buying that marvelous was 5'9"
