In the current (old) code there were 5 element groups: front, side, back, non-acrobatic, and dismount.
The side element group included arabians, roll-outs, etc. By doing a roll out you might avoid landing deductions, but there are still requirements for how those skills are supposed to finish. In the new code of points the side element group was eliminated - which I'm ok with.
Something I saw on the women's side that was disappointing and I hope changes is the lack of required diversity in tumbling passes. Simone did a full twisting double layout, a half twisting double layout, a double twisting double tuck, and a full twisting double tuck. It was absolutely amazing and beautiful. However, I was much more impressed with the diversity of Aly's passes which included about as much diversity of skills as imaginable. If they were competing in the men's code Aly's floor routine filled all the element groups, while Simone was missing two (front and side). I don't mean to take anything away from Simone, or suggest that she couldn't do it, but rather I just think it's interesting how different the code of points is for each gender.
