I actually found this very interesting and challenging. There are many ways you can get stuck optimizing a bad line. With all of Kjs R# levels destroying my self-esteem, this is a welcome reprieve. Very well crafted! This was very nice. I had variations of 110 and even one 108, before I got 106. :)) I'm not sure I have enough Pathology Aptitude to solve but this is a fun sequencing situation to unravel!
