My guess is they removed it because she was wildly inconsistent with it.I think Roberson’s front aerial was okay, but I wonder why she has not stuck to the layout mount. In the video @gymfan posted, it looks good.
This gymnast should do ONE split position in her exercise to fulfill the requirements, and not a single one more. She’s only losing points every time she tries to split her legs, including straddle.
Agreed that she should only do one split. All the CV in the world cannot make up for the deductions she should incur with having four different split elements.
