[MN] What to expect?

Context: My ex and I had child support court today. We didn't have a support order in place and decided to deviate to a support cost of $0 inleau of school tuition and curriculum costs to be covered (up to $3k a year). His original support calculation was $430 monthly and we did in fact deviate to a lower amount to work on salvaging some coparenting relationship.

Relationship never got better and I came into a rough financial situation and decided to get a support order in place.

ANYWAY, today in court (we both went without representation), the judge asked us both if we wanted to omit our initial deviation from our judgment or leave it in there.

I'm under the impression that since I will be receiving more in child support regardless, I can just use part of that for school tuition. I supported getting rid of the tuition/curriculum cost agreement for a flat child support order.

My ex on the other hand was under the impression that by leaving that agreement in our judgment, it will reduce the cost of his child support amount. He advocated for keeping the judgement as is.

Now, Correct me if I'm wrong, but those would be TWO totally separate payments and the tuition cost would'nt affect child support calculations what so ever? I'm not sure if he was expecting to get out of any kind of support order or what. He did say that he wanted to keep his support cost lower, but I think with the added tuition cost he would actually be paying even more?

Did he unknowingly screw himself because of his lack of understanding, or am I over thinking this? And what are the chances the judge will actually rule to keep the tuition/curriculum costs in the judgment along with a support agreement? I'm not looking to rob the guy, but at the same time he's made any kind of coparenting relationship impossible.

Waiting on a judgment, but it sounds like he doesn't have too much to decide on. Either way he'll be paying more that he was initially. I'm pretty unseasoned in a court setting so I wanted some input from others who might know better. Thanks!
