So let me get this straight: you attached files into a PDF which is only supported (or even notified!) if you install Adobe Acrobat Reader? I've been reading this document with the PDF reader built into Windows 10 and it didn't even know there were files attached. Ditto Preview on the Mac.
I've got to ask the question: why did you do that? I've now got to install Adobe's software on my machine to get these files. But because of well-known security problems with Adobe software I've got to do this in a clean isolated install just to get the spreadsheets (and even then I don't know if they are vulnerable to infection). This is a nightmare. Perhaps in future releases of this document you could just stick to including them in printed form in an Appendix?
