Well, so chances for a supertalent to be with 8 talent or more even from youth10 and one who set 4 times talent are 0.02%... chances for 9 talent are 0.0007% and chances for 10 talent are 0.0000186%, chances for 8.3 talent above are 0.009% (again, when the talent of the normal player is 5, Pucciol is youth8 kid so his talent is max 4.8 and probably lower which means he was even more lucky).
Well, don't think someone will pass him in talent anytime soon, or ever get close to that, as those chances means like 1 for every 11000 supertalents (and maybe bit less, as here I talk about supertalents with 5 talent starting talent and not all are like that), and it'll take some time to preduce such 11000 supertalents...
