I'm not sure what you're trying to figure out.  Trying to figure out the
compression ratio of the image from the holding memory doesn't make a lot
of sense.

Here's an example of what the compression really looks like for the image
on disk:

	rsp-isv-mz.123-8.T	23716416 bytes
	rsp-isv-.BIN		52859740 bytes (uncompressed)

	rsp-isv-mz.124-5	25912552 bytes
	rsp-isv-.BIN		59203996 bytes (uncompressed)

So the compression is greater than 50% in both cases.
