He does that, I don't want to say "a lot," but relatively consistently throughout his career. He'll have 6, 8, 10 game hot streaks.
What he needs to do is eliminate the the 5-7 game pointless streaks he goes on (Laf needs to do this too).
Of course that's very hard to do when you aren't on the power play. You don't get those free 30% point boosts, but, if you are going to be a high-end offensive talent you can't go cold for as long as Laf and Kakko do.
Kakko went cold for 20 games to start this season. He has to find a way to drive his line, can't just let it go that cold.
That's how you turn a 40 point no-power play season into a 55 point no-power play season.
