Hi Skschlag,
From the FIG update Nov 2016:
10. Question: A gymnast completely finishes the landing of a tumbling pass; then uses a jump to
prone as a transition. Is there an E‐jury deduction for this jump to prone?
Answer: No, there is no deduction for a jump to prone unless it is directly from a tumbling pass
with a rebound action or performed in order to avoid the completion of the landing.
Jumps to prone may, like any transition, receive form deductions, but it is unlikely unless it is an egregious mistake. We are unlikely to see cool jumps like Brin Bevens 2.5 drop anymore :-(
