Technically I find some of these definitions slightly misleading (“turn” is not a position but a skill, for example-- they could’ve clarified by saying “turn position”; wolf jumps need to go to horizontal, above is not required but nice; scales don’t technically need 180-degree split to be a scale, though they do need it for international elite credit; things like this). But I still imagine this is very helpful for new fans.
Frankly I find Sportseverywhere frequently gets details like these slightly wrong in most of their videos, though I appreciate the gymnastics content on YouTube.
