I mean, my vehicle doesn't reach top speed right off the bat no matter the hurry I am in. It's not exactly in their hands, right. They just started their journey. If they were in outer space, I wouldn't have any problem with assuming full speed.
We also have to consider that DB consistently depict ships as, "energy trail and go", a rather simplistic approach.
It is depicted that they were trying to rush,
It is depicted that ships, even ancient ones, accelerate to top speed at a rate so fast we literally cannot tell from the animation, or the panels, possibly because it doesn't really matter to the writter or animators.
And to top it all off, we are also scaling to a value that's extremely below what the ship should be capable of. (There are some indications that they were coming from another galaxy, yet, I only used the minimum 4.2ly distance).
In my personal opinion, Piccolo scaling to 36051c is plausible enough. But could we agree on a likely, or possibly scaling, then?
Don't they? Both Piccolo's and Vegeta's did.
Nah. The calcs, as in, the math, only used the distance, and a timeframe.
The sections explaining why said characters scale to the calculated values aren't part of the calc itself.
Jiren's case is fine. How will the entire scaling chain look if we applied the top result of the spaceship we know to Jiren's speed? Since not many characters scale above him, I believe digesting those numbers would be much easier.
At the of the Black Arc, SSJB characters are placed at "far faster than 6 billion times lightspeed", then, in the TOP arc, Jiren, and MUI level characters are 42.9 billions times c'
After that, characters are "far faster than 42.9 billion"
Gas has his space feat, which can lead to results in the trillions, or quadrillions depending on the method, but as of now, he is far faster than 42.9 billion.
Still, god tiers such as Whis, Beerus, and SSJB fusions scale 50x higher than that as SSJ Gogeta scales to SSJ Broly, IIRC. Beerus and Whis can scale above Gas' calc when it's done.
