With the IF and IS instantiations and grammatical-function ranking, we find many more RSH than SSH and many more RET than "pure" CON (i.e., without counting Establishments); indeed, in the IS instantiation with GFTHERELIN ranking, RET are the second most common transition.
rule 2 (BFP) is verified with is instantiations only at the .05 level, and with IF instantiations only if second-person pronouns are counted as realizations of CFs.
