Hmm, I thought I had been clear. I will try to be more direct: Given the option, I would *only* download the original, non-lossy-compressed data. At the expense of time, yes. I don't think Graeme's example is very representative of our work, sorry. As long as the option between the two is warranted, I don't care. I just don't see the point for the very same reasons Kay has very clearly exposed.
