It works pretty slick when you only use it as ADVISORY. There are corrections shown every few thousand feet in a rnav arrival, but the Vnav calculations are normally within +/- 100ft of what you really need, or what would happen with auto throttles and full Vnav certification. Not bad for 1980's technology....
