I remember reading the exact meaning of GETS, MISSES etc in Steve Adam's book years ago; I don't remember the answer but I recall it wasn't perfectly intuitive. I haven't the book handy and I failed to find the detailed definition anywhere else, sorry.
Anyway from a practical point of view - MISSES should be almost zero and several orders of magnitude less than GETS, whatever the definition; so what you are experiencing is definitely an issue ...
