For example, I just ran a sample calculation assuming mother had a monthly income of $2,000 and father has a monthly income of $6,000. With each parent spending 182.5 days with the child (perfect 50/50 split) father would pay $492 per month to mother.

Due to the disparity in incomes, even if father spends 215 days with the child and mother has 150 days of visitation, father would still have to pay $229 per month to mother.

In fact, with these numbers mother would receive child support as long as she spends at least 122 days with the child. Only if her days drop to 121 or less would she have to pay. At 121 days of visitation, mother would have to pay $5 per month to father.
