OK, that makes sense.

Oh, and an experiment that says "we looked at this, and we saw nothing unexpected" is still a good thing. It would be very unwise not to look because we expect to see nothing.

I agree, but the issue is not "was the experiment worth doing", it's "does it have anything to say about the interpretation of the MAGIC experiment". Owing to the shortfall in predictive power in regard to the Planck scale, I would say it does not. Indeed, it sounds like a positive result by HETE would actually be a refutation of the MAGIC interpretation as a quantum gravity effect-- on the grounds of it not seing
enough of an effect.
