Caroline Z gets decent GOE's on her 3/3 and solo 3F because she has good in-air position (if not height or distance), and tidy landing position. You rarely see her struggling for the landing (she falls if she really under-rotates, but otherwise it's always a tidy landing), the way Emily seems to struggle for every one of them. She doesn't telegraph her jump preparations the way Carolina does, and she does smooth, nice footwork into her solo 3F. Plus she lands the 3F with her arms over her hand, coming down prettily. It counts as a difficult variation, and shows control and body-awareness.
I'm not saying she has the best jumps, but she definitely deserves the GOE's that she gets. I suggest those confused by how jump GOE's are given to go and read the ISU rules before coming to bash skaters on these boards...
ETA: on the swervy entry for the lutz, Caroline under-rotated every single one of them this season, I believe. They put the hardest jumps in the second half because they garner the most points that way. Mirai has both of her 3 lutzes in the second half this season, even though she had trouble rotating the second one even when they were far apart (at national's last year, for instance; if she had rotated that second lutz, she would've beaten Caroline by more points). And this season I think Mirai has had at least one lutz downgraded in every LP.
I think the skaters can probably fully rotate these jumps in practice, in isolation, so then it makes sense to get the 10% bonus on the hardest jumps. But the fatigue and stress of the competition means that they often run out of steam in the second half -- I think this was (rightly) the rationale for rewarding jumps in the second half. For skaters who consistently under-rotates jumps in the second half, I wonder if it doesn't make sense to shuffle the jumps around...
