Hello Ben, the goal of the guide is to be a practical tool to help you determine which plants to grow near each other and which to grow far apart. There are no the kind explanations you're searching.
In the permies affiliate management section, it seems there's no correspondance between the number of total unique clicks (in the attached screenshot there are 21 clicks) and the number of unique cicks per product (please see the attached screenshot that shows that for the "all of the PDC and ATC (177 hours) as HD download" product there are just 2 unique clicks).
Thanks Paul...I have seen somewhere in my account a page where there was a list of all the people who downladed our pdf. I had understood they were not only those who bought the pdf. There was the name and their email in the list I saw but I don't find it, thanks in advance
