Taken from the first response:
so if your logic bonus is zero your logic gives you no benefit when on a node and no benefit when off a node.When on a node or in town, you will absorb an extra (Logic Bonus/5) experience every pulse. When in a hunting area, you will absorb an extra (Logic Bonus/7) per pulse.
and like I said, your BONUS is what matters, so whether it's 56 (0), 85 (0) or 95 (0) due to racial modifiers, your bonus is still zero so there will be no difference with regards to xp absorption.
