Do judges in Family Law ever rule against child support /parenting time guidelines posted on County website?

Judges rule on the information that is presented to them.  Starting with accurate income, health insurance costs, daycare, parenting days, and other information requested on the worksheet will help the Judge do this.   If the information on the worksheet  results in a significant and continuing change, the Court has the authority to modify the support. Often, that change is defined by whether it is a 15% or more change.   Since the tax deductions are only changing slightly, I am wondering if the change is less than 15%.  If the income percentages are that close, I often encourage and will ask the Judge to keep it equal for both the tax exemptions and payment of non covered medical costs (out of pocket medical bills) because it is easy for both parents to remember.  It makes the math easier, too.   A change in parenting time is a separate matter.  If you only want to make a slight change to holidays, remember that you and the other parent can always agree to make changes, just confirm it in writing.  You may also want to use Court Mediation through the Conciliation Court Services office in Maricopa to address these smaller items.
