Since your daughter stopped skating, half loops were reclassified as loop jumps, so a Flip-half-loop is now a combination, not a sequence. In some of the levels, only two jumps are allowed in a combination, so a flip-half-loop-salchow is a three-jump combination now, whereas it would have been a sequence when your daughter skated.
I think (check me on this) if the level only allows two jumps in a combination and the skater does three, they get no points for the third jump under IJS scoring rules. Is there a penalty under 6.0 or IJS?
However, the definition of a sequence is now more accurate, imo, because the half-loop really didn't require additional steps before the salchow. It wasn't a "listed jump" so the older rule allowed it to create the sequence. Once they listed it as an Loop variant, it changed the sequence to a combination.
Under the current rules:
A combination would be a Waltz-Loop or an Axel-Loop: no additional steps or changes.
A sequence would be a Loop-Waltz or a Loop-Axel: the Axel requires a FO takeoff edge, which is an "additional step."
I still wonder if a CW jump/CCW lutz was considered a sequence or a combination. Is there really a rule?
Maybe her coach just didn't want it included for some reason.
