SN1987A was distanced at c187kly by knowing that the light from it illuminated a ring of gas surrounding it about 1 year later. It seems to me that the exponential CDK model would move SN1987A MUCH further away, off the top of my head hundreds or even thousands of times further away. This is because given that SN1987A is a lot more than 6000ly away light must have been moving much faster then, so the triangle baseline gets a LOT bigger....

I think the perceived frame rate change answers this. The light actually jumped across the 1 light year distance very quickly, but we see it in a slow motion which exactly compensates because the light is arriving more slowly now.

Too neat, huh?

So, do we see everything happening hundreds (thousands/millions/billions/trillions) of times slower than it actually happened according to the distance in the CDK universe? Thinking about that and imagining the photon stream spreading out in time as it slows makes my objections nonsense, as I suspected. My memory of subtense bar and theodolite doesn't destroy Settlefield's universe.
