Reply to Numark N4 pitch fader resolution in Traktor?

Help needed from N4 owners!
Could someone please tell me how's the resolution of the N4's pitch fader in Traktor? For example at 8% pitch range, how big are the steps?
Also, I am interested in the quality of the sound card inside the N4.. heck, I'm interested in a full-on review so any thoughts and impressions are useful to me (I can't try it out before buying it so I have to fish for info this way).

Thank you in advance
