it's a drop weight. it should be accurate pending the user.
gravity is a beautiful thing. read the directions and have at it.
i consider a dropweight system to be as accurate as one can get.
likely, the only thing that would cause inaccuracy of the machine would be a misplaced sticker on the bar.
heck, it may not even have a sticker and be engraved for all i know.
