My spouse and I have agreed on a lower amount of child support than the law allows.?

My spouse and I are in the midst of a divorce where we intend to share custody of the kids. I will have the kids for 4 days a week some weeks and she will have them 4 days a week some weeks. We live in close proximity to each other and the kids are adjusting well to the new living situation. We both make decent salaries and we want to deviate from the standard child support amounts. According to the courts they tend to do that which is "in the best interest of the children." That being said, is it possible that the courts will order a higher child support than the amount asked for in the decree? If so is there any recourse?
