Sounds like you are getting somewhere Merry.
The idea of the Leeds sorting is that you don't know who most, if not all, of them are and you group them and hope some of them have enough of a tree to work it out.
For ancestry I have 2 groups called maternal and paternal and I try to get everyone into one of those. I also have an NFI group. The names get a bit tricky as there aren't enough dots but if you can identify any branches then you can label those, if you can't stick with numbers.
I also did the spreadsheet thing twice before I felt confident I had a grasp on it. It helped that I came across people I have seen with trees before so I had an idea of relationships and Dad had a cousin and cousins son who had tested so between them I could rule matches paternal or maternal quite easily.
