Accurate to within 50ns, +/- the drive speed deviation. During the read startup, I wait for the next bitcell period before starting the read because you can have a bitcell appear directly under the start of the index pulse. This is the only time you will get a shift. You can use the analyzer and click READ TRACK to get an idea of how often data shifts, and you can see it is by one bitcell period at most (unless you have a drive with severe speed issues, which I have seen).
