yes, I changed them back (wasn't logged in).

Raid efficiency isn't the same as the usual efficiency. This is what I used:

the power required in raid is (5 + front line pwr) / 2.

Thus, assuming you are using 5 cards in your front line, the power efficiency of raid cards is computed using the formula (Max ATK) / (PWR required +1)
