I saw some pilots who held an IR who did a “VFR bridge course” from MP to SP for a type rating (all that is required) and then their authority would only give a VFR type rating for SP while allowing MP/IR on the grounds that they didn’t do some SP instrument approaches in the bridge course (which isn’t required).
the bridge course is more about rejects and emergencies on your own as I understand.
so even the authorities are confused on this subject 🤪
