Hi. For USAG Level 6 beam I do a back-walkover back walkover series. I have heard there is a rule that you cannot repeat a skill more than 3 times. So if I don’t go for it on the first time, do I have to change my series to a handstand back walkover to avoid that deduction? Also how much of a deduction is it? I do not have a round-off or back handspring yet, so I will not be able to replace if with those instead.
