I wonder how much of a problem it is to stop practice for a week.
We're talking workaholic piano geniuses here.
And although the other 2 had their full practice schedule okayed, it's not like they do not have their own troubles.
Also, Kousei seems to be several notches above the other two in terms of genius.

So is that week that detrimental, or does it serve as a breather where he can sort all of his feelings and be ready at the very last second to let his genius express itself?
