Hi Bill,
Congratulations on the book - it looks like a fair chunk of work!
If you're interested ... due to the underlying workings of e-mail, files are re-encoded (translated, if you will) from their native representation to text using a mechanism known as "MIME encoding" (this is for cross-compatibility between e-mail systems). As with translating English to German, there's a tendency for the encoded/translated version to be a bit longer - it generally increases the size by 1/8th or more. And yes, the errors, etc, for this could be clearer ...
No idea if that helps...
P.S. Was your signature quote the Fred Thompson who played DA Arthur Branch in Law & Order? I liked him in that.
