Can anyone tell me if converting EBUP to LRF is always this much of a storage hog?
Was this a failure on Sony's part to not be able to properly display an EBUB book or a failure of the creator of the EPUB version for not using standards?

Yes, the resulting LRF is still 18MB.
I really don't know why the file is so larger, if the "useful" content is still the same – same book, same text.
I don't believe the LRF file format is so inefficient as to waste so much more space in tags than with the actual book's content – we are talking of an increase of 640%, or almost 7 bytes in tags for each byte of useful information.
I am guessing it is probably something to do with calibre's conversion algorithm. As any generic algorithm, capable of converting whatever structure the authors create in a book, it cannot be as efficient as someone manually formating a book and placing only the right tags at the right places.
Again, I am only guessing, as I have never seen neither these file format documentations nor calibre's source code.
And, by the way, even if the increased size is due to calibre's algorithm I cannot complain about the application. I really prefer to waste this space if the alternative is not being able to read the book...
I was also curious about why the EPUB version didn't display properly. I sent a message to Pragmatic informing the problem, and I will post the reply here if I ever receive it.
