I don't believe the sim. engine is able to detect team formations. It's just about comparing player versus players where they acting in same/opposite zones. I never use a specific formation, Taking into account my full squad capability every season. So i prefer to use 3 formations; the main formation is built in the manner of maximize Team AvQ. Slot 2 is saved as high AvQ alternative. Slot 3 is for an option/tactical formation to aiming oppo.'s weakest roles on pitch. Slot 4 is always empty to slightly adjust positions/compare new formations in a clear view.
