Are speed upscales allowed here?

[Averroes1]

Let's say character A is mach 6500 (6.5x MHS+)
And another character B absolutely destroys character A in speed.
Can this character upscale to baseline Sub-Rel?

Speed upscale is allowed , but such a largegap grom mach 6500 to sub would be to big of a gap in most cases

Even if Chr. B views Chr. A in slow motion?

Even if Chr. B views Chr. A in slow motion?

it is very hard to get an above 1,3× upscale accepted , but if B can see A in slow motion i would be fine

Is there any examples of a speed upscale that you can find?

Dragon Ball characters upscale to Relativistic from Roshi's Sub-Rel+ moon feat.
