Boxing-11 guy dodges on a 9 or lower (12 or lower on a retreat)
Boxing-20 guy dodges on a 9 or lower (12 or lower on a retreat)

However, Boxing - 20 guy can parry on a 13 without retreating. Keep in mind that what you call blocking in boxing would be a parry in GURPS terms, so, such an action is quite likely.
