Obito even before he "died" wasn't too shabby in his speed.

As soon as he got his Sharingan and some confidence, he was able to fight the Jonin along with Kakashi. The Jonin who was comparable in speed to Kakashi himself.

And how fast is Kakashi as a kid you ask? Well, we know he was fast enough to use Chidori. We know Sasuke had to train to Rock Lee (without weights) levels of speed to even use Chidori. So Kakashi has to be that speed too at least.

Of course Obito had the Sharingan to help predict movements. But Sasuke vs Rock Lee showed what happened if someone is far faster than you; the Sharingan can predict, but the body can't react. Obito was able to react. So he can fight, with the Sharingan, at levels of speed similar to Rock Lee or Kakashi.

And that's just as a kid, before Hashi cells and before Madara training.

Obito being very fast isn't so farfetched. He's probably not quite KCM speeds, but it's obvious he's comparable.
