In reference to @Apeiros's count of 2 for my actions, I am assuming he means my Mathematics roll being one and then my Divination roll being another. I believe these are supposed to be in the same action.
I reread the the Mathematics spell casting section (well... only until I found something that supports or nullifies my stance).
At first I'm thinking "it says it right there,"
configuring the planets takes at least one round. But then the next paragraph suggests (to me at least) that the spell is cast immediately.
This seems a bit open to interpretation, so as always, if @Apeiros disagrees then I will bow to his dominance.
