Thank you for the link to the post! This was definitely the harder exercise for me – I think because I think more in terms of the LAND, and this exercise was about the IN/OUT bits, to borrow the terms from the linked post. I also had some trouble getting an idea that depended on the sustained matching, as opposed to having some matching going on as a highlight at one point. Then I took a break to do exercise #3, and the previous linked video essay shook something loose, and I had an idea! (That also continued my Ye Zun roll.) I suspect this will end up having been the hardest exercise for me, as I have a vid already for #3, solid ideas for #4-6, and while #7 confounds me, I'm sure there'll be additional instruction when it rolls around.
