The commission upheld the definition of downward elbows as only applying to strikes that move directly from ceiling to floor, or "12 to 6," and agreed that the blows would remain illegal.
Blows delivered with any angle other than ceiling to floor, i.e. straight elbows to the top of the head delivered with an opponent in your guard, are not considered illegal strikes.
