I believe it is? In the 9.4 box, the RO-FF on>repulsion. It wouldn't be to a flat back, but to standing on the floor. No flip. Like the one L6/7 vault, but not to mats. I know this is a legal vault in USAIGC Silver, and that’s the way I read it here? But I fully admit, I’m no Xcel expert! Good luck!
ETA: never mind! I was thinking Diamond. No, that wouldn’t be allowed in XP. Sorry!
