I don't think your experiment measures OWLS. I don't think it *doesn't*
measure OWLS. It's not a scientific question. I'm not saying this because of
any special property of one-way light speed versus, say, two-way light
speed. I'm saying it because I don't think that any discussion about
measuring properties of the world can ever be scientific. All that's
verifiably real is (a) what actually happens, and (b) what theory predicts
will happen. In this case, theory predicts a certain difference in the
readings of the clocks, and that's almost certainly the difference that we'd
find if we did the experiment. What would we have established? Only the
accuracy of the theory in this particular instance. Anything beyond that is
speculation, at best theory-dependent and at worst meaningless.

I just don't think that discussions about theory-independent properties of
the world will ever lead anywhere. To avoid wandering into a metaphysical
swamp, you need to either talk about experiments as themselves, or else talk
about constraining the free parameters of a theory under the assumption that
the theory is true.

Ever read the MMX? The result did not agree with the current theory.
When that happens it must be explained why the results were different
from the expected, or the theory needs to be modified to predict what
has been shown to be the actual result.
