Also, I'm not sure why being allowed to do three 3Lz would give skaters more possibilities. I assume the reason this skater wants to do a solo 3Lz in addition to the combo and the sequence is because she can do an enhanced 3Lz with difficult or creative entry, exit, and/or air position, but can't combine those enhancements with the combination or sequence.
But in most cases, if a skater can do 3Lz+2A, she could also do a 2A in sequence after a different triple jump instead. Otherwise, to show off more ways to combine or enhance her favorite (or highest scoring) jump would usually require her to leave out some possibilities. So we'd get even more skaters avoiding the full variety of jump takeoffs.
