I don't really get the scoring system...cause some of these dives look fine but they're just getting a 7
It's really about perfection. They dock points if your legs aren't fully straight and parallel, if your splash is too big, if your entry is not totally vertical, if your feet aren't aligned and so on and so forth... Tiny details that us mortals don't notice
I don't see it myself but live commentary will go like "argh, there's a thin gap between his legs" and on in replay I'm "ohhh I see it, he's right"
