I'll make an exception and reply to a bold post of yours
Yeah it will be a surprise if Lankri ever makes it to the top 200 but I hope she'll at least give it a go for a full season like Keren does (and most Israelis at that level never did, e.g. Astrugo
And for the record, there have been cases of players who did nothing until they were 25 and then broke into the top 100, like Bammer (who was even top 20) and Barrois. And we don't even have to look outside: Tzipi (though hovering around #150-200 for much of her twenties) is probably the oldest ever top-100 debutant at age 34.
Bottom line is give the girl more time to play before you send her home.
