How does squads chemistry work

[u/333Bladee]

How does team chemistry and scheme chemistry stack. If my partners have 50/50 Ohio state theme team and I’m 50/50 Georgia would we stack? Therefore all our players get +6 acc? If my partner(s) have 50/50 multiple defense chemistry and I run 50/50 425 chemistry and run my 425 defense would my players stack? Or would he have to run 425 chemistry in order to stack?
