The tick tock BHS fulfills the acro requirement as long as she connects it; if she's not connecting the BHSs in addition to falling, that's a wise choice on the part of her coach. (Remember that losing the connection knocks out the series requirement and comes off SV.) If that's all the acro in her routine, by my read she would have a full 10.0 SV but could incur the comparatively small composition deduction. I assume she has the other necessaries. In the L8 routines I've seen, I have not seen very many FWOs, FHSs, or ROs performed that incurred no deductions, so it really is going to be at best a wash for a lot of athletes in terms of scores.
