Silver18 has only posted the *.pdf version, at least as far as I know about.
If the *.pdf version is a generated file (such as from some non-Adobe word processor), the source has not been posted.
The guide was written for the K5 because that is all Silver18 had to work with.
You could probably PM Silver18 and ask what form/format to send/post the K4 additions.
I don't see any copyright or license statement in the document (but I am pretty sure its "Country of Original Publication" was Canada (this site) ), so it is probably still under the automatic copyright granted the original author.
So you could PM Silver18 for permission to derive a K4 guide from his Intellectual Property.
(Unless Silver18 adds an "Open Document" license to the next version, but don't hold your breath, the filename still has spaces in it after 4 revisions.)
