Yeah, I don't really care for this and its breakdowns. Also, it lists specific groups and people in here rather than just limiting itself to positions.
One could put together an even more complex breakdown of sedeplenists.
I would not use Conclavist and Non-Conclavist as the top-level distinction, but I guess you could carve it up in different ways. Most Sedevacantists don't think of the Conclavist issue, but that comes as a consequence of their core position and is little more than an idle afterthought to most of them.
