How many supports are in the GBA games in per unit?

I am curious about the maximum number of supports that a unit can have. If I ever plan on making a FE ROM Hack or will ever make one in the future, I need to know in advance.

In almost every GBA game, the support limit is 5 convos per unit. That means 1 A support and 1 B, and so on.

If you mean the max number of support patterns an unit can have, then I think the max number is 7.

This is actually one of the main reasons I steered toward the Lex Talionis Engine.
There’s no limits at all to the number of supports a unit can have with LT. I’m doing the DS thing where the MC’s have supports with every single unit.

Is it worth mentioning FE6 can have ten supports per character?
