It does not say it in the current manual for the Korg Pitchblack but in the manual I had about five years ago it said that it was more accurate when used in Strobe Mode verses Needle Mode.The point in this video that most digital display tuners can't 'display' as finely as the spec on the tuners' accuracy is often overlooked by people.
Also, for those who tout Polytunes but use it in needle mode, they're not nearly as precise as when they're running in strobe.
