I would guess with an ideal op amp, both pot configurations should be the same (assuming op amp output independent of load). Also, both pot configurations should have same relationship of wiper voltage to pot position, as long as no significant current is drawn from the wiper, the way I see it. I'm open to other theories...
The 3 pF shouldn't affect the comparison if the op am is ideal I would think -- but often simulations defy my intuition!
