The average velocity across the entire trip would have to be several hundred km/s. Average. Peak velocity would have to be a lot higher, to account for acceleration and deceleration. They're claiming to have built a torch drive that beats the thrust power of all other (currently existing or in early development) propulsion methods by an order of magnitude. Extraordinary claims require extraordinary evidence.

Yes, they should show not tell. But this wouldn’t be Russia’s first space travel breakthrough by a long shot. I wouldn’t jump to disbelief so readily.
