I would guess a minimum of 2-3 years. At least that's how long it took Liza to get her 3A back, and she had better foundational technique and was working with arguably the best technical coach in the world.If this is a true reworking of jumps due to puberty, doesn’t it take a bit of time to relearn jumps? Like, say, a year? If that’s the case, the timing is actually good. She could have everything back together and be an even better skater in time for the Olympics.
