We don't have a procedures expert here.
I beg to differ on this point. You wouldn't believe just how many of us look into topics such as this and end up shaking our heads and moving to the next topic. I can't speak for TERPs procedures but, with PANS Ops, what do you think is the REAL significance of an IAF?
Some, like me, as a (former) airline pilot have been looking into TERPs since just after the ark sailed.
PANS-OPS is a much tougher nut to crack because ICAO tries to make the criteria and flight procedures sound so neat and uniform. Yet, each state is free to do its own "spin" on the PANS-OPS criteria.
Remember Dubrovnik?
