Not really, and even one of the researchers of the G1 blog(MomoUra) doesn't think Vader's capable of blitzing, the very same blog everyone loves to keep barking up. I'm sure you can even pull up various examples in fiction where characters multitude of times faster than the other and the other was still able to keep up.
Well I'm not a calc guy, I just kinda assumed the general consensus for Vader and Obito was around planetary level so it made sense. We don't know exactly what method or calc they used that got that number, I've also heard that Naruto's earth is a lot bigger than IRL's so maybe that can also be the cause of it, an generally vaporisation is greater than evisceration.
Let's put it this way a human eye is capable of processing images between 30-60 frames per second, an average human is capable of perceiving a ferrari sports car driving and moving even when going up to 330 km/h. Sure that car is moving so much faster but humans can still perceive it on the track if briefly. Now you take someone who has superb field awareness with the Sharingan, extrasensory senses and superhuman vision, an now it doesn't seem so blitz worthy without Vader being several leagues above him in speed.
So with this established and even the G1 researcher(referring to MomoUra) in order for a comfortable blitz to happen Vader would have to have to be so astronomically faster unless if you can give me examples, even then it's always flimsy in fiction and every series/character treats it differently(example that comes to mind is Scar vs Bradley from fullmetal alchemist brotherhood), thus far it seems like every interpretation(apart from Weekly's I guess) has both Anakin and Obito in the same wave length roughly in speed so there's a lot of wiggle room to debate, an since basically every power scaling I've seen has them pretty close in stats a lot of people really drew from the MU as a stats vs haxs debate, but with it being so close to where haxs can actually be a genuine threat to Vader if he doesn't do anything.
I'm glad you enjoyed the episode, I loved the episode personally. The outcome of the episode doesn't really make me too upset because I'm aware no matter how hard myself or anyone else DB's interpretation isn't going to just chance, an since I was always 50/50 on the debating side so I was fine with either Vader winning or Obito winning. I'm not forcing any narrative nor do I want to be chewed out or shit flung at just for throwing a different hat into the ring, I'm very much aware that DB is far from perfect and that they've made blunders in the past like with Ben 10 vs Hal and even ignoring old DB when it was only Ben that was doing it all, I dunno maybe it's because I'm not so hardcore into the modern vs debating. Let's just agree to disagree with this subject, no harm no foul
But like Speedy said in the future if we want a discussion from them shit flinging and insult hurdling isn't going to be way to do it.
