I've had another good look at the file I made to test all these scenarios and still get the Kindle not recognising part ems for spacing. It also still gives inconsistent results for whole ems.
If you have the time I would be grateful if you (or anyone else) could look at the attached and see if it's my fault.
The problem of part ems not working in the attached files have been solved by @crutledge. See my next post.
