Elbow off pad: warning (1st), loss of round (2nd within match); Shoulder off-line / non-pulling hand off peg: warning; Slip out / forearm crossing center line: dependent on cause — if defender's fault, no foul; if attacker, warning
Why people argue about this
People often assume that if their opponent's elbow is off the pad once during a match, they get warned for it. However, the actual rule states that getting an elbow off the pad twice in one round results in a loss of that entire round, not just a warning. This confusion stems from misinterpreting the frequency requirement for penalties within a single round.
