Yes - I have a suspicion that you may have missed exactly what FH says - it and Mike Tate say (for example) "Great (x3) Great-Aunt". Note that "Great" appears **twice** in that relationship. It's horribly easy to read "Great (x3) Great-Aunt" as
"Great (x3) Aunt" (been there, done that!) because you don't expect the second "great". Most of us would write
"Great (x4) Aunt" - maybe Calico Pie did it like that so that the number of greats in the first part, matched the number of greats in the sibling 3G-grandparent.
