@@duck6246 that is more of a matter of opinion, maybe he doesn't grow as fast as others, maybe he just isn't that tall, or maybe it's that the age gaps between each piece aren't that big. Why would they lower the age for this piece but not harder pieces like H. R. 2 if they are indeed doing that? Not everyone uploads performances in terms of time, for all we know he's in high school now and these are old recordings, you never know.
