aterpster, it's the same like for the most of us called Jeppesen, if that's what you're referring to.
BTW in your example MSA is predicated on the RNAV way point RW 18 therefore it's not sectored and logically it can't be it's not a nav aid after all. Yet MSA is quite useful if you simply climb to MSA regardless of your position as long as you're within 25 NM and above MSA you're good.
