For the part of artillery spotting: (double atack and cut-in)

- "2 x Main + Sec + Seaplane" is considered a bybrid setup which provides chances for both DA & CI as you said.

- "2 x Main + Main + Seaplane" is a variation of the basic DA setup. It only triggers daytime double attack.

Depending on the type of your AA gun (Main or Secondary), your setup would follow either of the two above. What's worthy mentioning is that machine guns are considered neither main or secondary and will not affect the attack mode.
