If we correct the absorptivity for Earth IR and take the low end view factor, I get your 522 W/​m2. That looks like a ~1% increase in total cost for ODCs if you’re right.
I was using 550 km, so I agree that higher up, you would have more net radiation leaving the radiator.
As for your bent configuration, that is creative to avoid the sun incidence. However, then you would have radiation from the solar panels to the radiator, and since the solar panels will be warmer than the Earth, I think it will work out worse overall.
Agree loss from averaging over radiator temp looks.
I’m glad it was helpful!

Incomplete?
Your other points make sense.
