Makes no difference (And why should it...)
The best I can get to is 0.06BPM and thats using 6% pitch
If I switch to 10% (which I usually need to) then it goes in 0.09 - 0.11
The pitch fader has to move quite some way to register a change too, a little nudge won't affect the numbers at all. My Denon MC6000 on Traktor could get right into the hundredths..
