 The four digits represent scores of "ippon", "waza-ari", "yuko" and "koka" (which was still used at the time).A letter indicates a penalty of "shido", "chui", "keikoku" or "hansoku make", which (at the time) also registered a score of "koka", "yuko", "waza-ari" or "ippon", respectively, to the opponent.Penalties are escalated, thus 2 "shido" = "chui", 3 "shido" = "keikoku", 4 "shido" = "hansoku make", save that a penalty of "hansoku make" direct results in exclusion from the remainder of the competition, while if it results from escalation it does not.
