First of all, Kaioken multipliers shouldn't be ignored; it explicitly states it multiplies energy output, speed, and durability by X times. And actually, I can't really think of "Bigger example outliers" but the other one on the list that comes to mind is Naruto. That actually does have some accepted multipliers; Choji has something call the Chili Pepper Pill which multiplies his power a hundred fold. It's consistent with Genin being 8-B and it's back up but his own attack having a Low 7-C calculation. And the Sound Ninja 4 have 10x multiplier statements in which they someone struggle with a single Genin in base but match Chunin who have 8-A feats with their transformations.
But anyway, I also mentioned that SSJ multipliers in the like tend to be very inconsistent; it was only 40-50x the first instance against Frieza in which 20x Kaioken literally matched Frieza's 50% mode, but SSJ completely overpowered his 100% form. Not to mention, Goku openly admitted that even against 100% Frieza, he was holding back the entire fight and at one point said he had no reason to continue fighting simply because "Frieza is too easy for him". And while Frieza did have limited stamina, even in his 100% form, he didn't instantly weaken. And he's always been shown to be much faster than 100% Frieza as he outpaced all those disks like they were nothing.
Now as for the topic at hand, we can use Kaioken multipliers for speed; saying it surpasses Whis' feat isn't really a counter argument because his speed feats are all casual. Sure he mentioned going full speed, but he's still in a relaxed state and those could just be bluffs. And actually, I disagree with other statements Cal knit picks; combat speed is consistently higher than flight speed. While that doesn't mean they aren't incapable of flight speed comparable to combat speed and even flight speed tends to be inconsistent in Dragon Ball; the heat of combat is where DB display their full speeds. Long term point A to Point B speed has always been unimpressive compared to the short term ones that happen on the battlefield. Ultra Instinct Goku never tried to fly from one side of the universe to the other; so his flight speed feats are still considered "Short burst flight speed or movement speed". That being said, the DBS cast should still be Massively FTL+ outright for other reasons, but I think it's still safe to say his true combat speed is much greater than any flight speed he's demonstrated.
I'm unsure about how to properly calculated all the various zenkais consisting of "Base Goku post Zenkai is stronger than Pre-Zenkai SSB/SSG Goku". I don't think those can be calculated, and I think the SSG to SSB assuming 20x for those is iffy. But examples of Kaioken being used should still be fair game.
