Yep - I think you are all right. AF sent me to TERPS school a long time ago - It might be the clearances on the approach end - but normally since the ILS brings you "lower" on the approach - you might have to have a more restrictive climbout on the MAP because you are penetrating the obstruction plane - LOC you are higher when you go missed and might not have the issue - which pushed you to a different approach panel because they can't share the MAP. By the way - passing grade out of TERPS school is 65% - Every time I look at an approach plate I'm thinking ' 35% of this could be crap. Be careful out there folks.
