Doubt I spent more time than that on actual practice either, except before some special event.
I've never understood how an Adult!-parent could allow/nay, encourage the #hrs/week immersions demanded--especially re sports
--but also in arts like music; prodigies excepted, of course: theirs is an almost inexorable path.
Just can't see how a kid can actually grok to comprehension, even the mass of standard H.S. courses, while sustaining these huge time-sinks.

(What I can't know is whether courses have been really dumbed-down, compared to my experience?--such that it's easy to budget the extra time?)
Scary that situation, if true, since the sheer amount of descriptive factoids has been growing exponentially since my entry.

Parents 2014; given the utter unpredictability of bizness, the zeitgeist, or even national cohesion: Y.P.B.
Fortunately you're smart enough to do the triage, even amidst the routine madness. (I coudn't.)
Luck!
