Difference between talent for technique and hard work, while Yuizaki was new at th technique/method she still had enough talent to get those results. The coach giving that small bit of advise is plausible (if not completely believable) for a technique he pioneered/developed in his own competition days..,
I prefer to look at it this way, Yuizaki loves shotput, but the regular method doesn’t suit her (or her body?). The new technique, while even unpracticed, has a lot more potential for her.
You’ve never had that “aha” moment caused by some “not really random” source? I see it as Yuizaki struggling with how to use the form properly. Sure, Oomiya helped with the “skip” assist, but the competing coach maybe said it in a way that “made sense” at a moment that mattered...?
Well, that’s the way I prefer to look at it, even if it’s not completely believable...
