Okay. So a few tips to point out is - Your overall running speed is increased immensely, this is a fact and a force to be reckonened with. So are the increased damage to leg-based taijutsu.
Let's say to deliver a lateral kick - You would appear in a flash before your opponent, catching them off guard - But alas that is all. The moment you perform the lateral kick your speed is regular according to your rank once more, much akin to swift release. Your kicks are powerful and deadly, but the moment you stop to deliver the attack you're visible again.
Refer to Rock Lee and Gaara's fight in the Chuunin exam - Everytime he appeared in from the blur his speed was normal again, but he appeared so fast at locations, that Gaara wasn't capable of moving his sand to said location before the blow would land.
So essentially - What I'm saying is, the move you just performed. You describe it as if you just flash through me. You do not, you suddenly appear before me in an immense flickering flash or so, and then delivers a speed regular to that your ninja rank - Kick to my chest, with increased power.
