Even bee himself indicates naruto use shuusin while in Km Mode which furhter backs up hadoukage's statement and makes your poor chakra control statement invalid.
Now the first time when naruto used his km mode speed against kisame he used too much speed thus injuring his leg, now at that moment his control of his speed wasnt profiecient like you said but thats because it was his first time using it.

When we saw km naruto evade the raikages full power speed punch that proves he learnt to control it better.
