I just did an experiment. I'm working on a mobi file trying to get my kindle 3
to show page numbers, so I've got the files handy. I have 11.9 KB of html in it, along
with some jpg images. When I rename the mobi as a zip file and unpack it I see the
same 11.9 KB of html. 11.9 KB divided by 128 is 95.2. When I look at the book on
my kindle it says there are 83 locations. 11.9 KB divided by 83 gives about 147 bytes per location. For another mobi file I made, the html is just over 464 KB, both in the source and in the unzipped mobi. The kindle says this one has 3135 locations. 464 KB divided by 128 is 3716. 464 KB divided by 3135 locations gives about 152 bytes per location. The larger file is almost all text.

My conclusion is that the size of the html in the mobi, divided by 150 should give a
fair approximation of the number of locations on the kindle.
