Fast trainer and gain as scout ranking?

[cookizzz]

I have not arranged many high intensity practice matches for players after reaching 6 star levels. In my limited records, two players gained around +90 in this situation.

Edit: To be more specific, one player gained +95 at age 19 and another gained +98 at age 20. No other 6 star player gained more than 90 through high intensity practice match in my 2 season record.
