Lytron, a fairly serious radiator manufacturer, chooses to specify radiator performance in terms of C/W, and does not appear to differentiate with respect to the actual size of the heat-load.
Now we could argue for days on whether or not such is exactly correct, but perhaps we could agree that such is "good enough".
Are we prepared to say "If it's good enough for Lytron, then that makes it good enough for us"?
I don't know the answer to that question, and the absence of any heat-load specific corrections in the Lytron data does not necessarily mean that it is not a significant factor.
At the end of the day, it's something which could be investigated by those with the equipment to do so (i.e. very, very few), or we can run with a set of testing guidelines today that allows a wider range of testers to participate, which is what seems to me to be sorely needed in this day and age where there is an absolute dearth of radiator test data short of Bill's efforts.
So again I ask, "What is the goal here?". Are we here to define a way in which we can agree on what "C" should mean for each unit, and in a way that allows more testers to participate. Should we then leave more detailed discussion on the exact correctness of such, and calculating the necessary correction factors by those with the equipment to do so.
I'd like to see more independently verifiable data out there.
