If whoever sent you that .pdf file wishes my feedback on the many errors and ommisions I found therein, I am clearly not difficult to contact. Clicking on my name in any message I post in these forums will always yield my email address. An inquiry to my email address (even a rude one) usually yields much more in the way of information than I post here, it being my current policy to restrict what I publish on these public forums.
If they wish to remain uninformed, that's their look-out, so long as they don't go, knowingly, pushing their bad data on others.
