I have RCL and RCL daily in side-by-side windows
In Common time (Proper 3, 4, 5, 6…) when I got to Proper 6 what is labeled as "Option I" in RCL is actually the semi-continuous reading (and isn't notated as semi-continuous or complementary)
In Daily RCL "Option I" is complementary and labeled as complementary, whereas "Option II" is semicontinuous.
So the two don't agree on complementary or semicontinuous with regards to the labeling of Option I or II.
- - my suggestion - - add the words complementary or semicontinuous in regular RCL
