 A group of `test cases' connected by joining lines
 is defined as a `test case disjunction' or symptomatically merged group (SMG).
 This is the analog of a `spider' in constraint diagrams~\cite{howse:spider}.
-Joining lines R2 and R3 form a Spider, or symptomatically merged group (SMG).
+Joining lines R2 and R3 form a Spider, or symptomatically merged group (SMG) comprised of three test~cases.
+The joining line R1 forms an SMG with two test~cases.
 %SMGs may be labelled.
