Question about combos in wings.

[Aqualys]

First of all, I wasn't sure in which section to post this. There's the "Suggestions/Questions" section, but no one really asks game-related questions there... anyway, I thought "General" was safe.

My question is about combos with cards that can be slotted into wings (for double effect). More specifically, the Tarou and Cramp combo. If I have a Cramp card in wings and two Tarou cards in accessories, is the bonus applied twice? Tarou card is 2 str, and the combo gives +3 str on top of that (+5 str total), so Cramp in wings and two Tarou would total to 10 str (the Cramp in wings applying the combo twice), beating Vanberk in the wings and two Mantis (total of 8 str). Right? Or wrong?

I hope that wasn't too confusing. Just in case, I'll make it more simple.

Tarou card in accessory #1 : 2 str
Tarou card in accessory #2 : 2 str
Cramp card in wings - combo with Tarou card #1 : +3 str
Cramp card in wings (double wing effect) - combo with Tarou card #2 : +3 str

Does it works that way? Or is the combo applied only once, despite the "double wing effect"?
