Question regarding ROP: Divine and Infernal

I think this question was answered a long time ago, but I can't find it.

I have two magi in my troupe that have decided to go opposite directions. One is dedicating himself to the infernal realm, and the other is serving the dominion.

The question is:

"Concerning Miracles and the Maleficia, do both methods' abilities advance as normal supernatural abilities, or do they advance as accelerated abilities?"

I'm not sure if I missed it, or whether I should assume that they advance as normal.

Normal supernatural abilities. These books were published before accelerated abilities were.

Thank You
