Double Empower?!?!?

OK. Just to make sure I have the math right...what would 4 doublings give you? 2+1+1+1=5?

Yup. The math isn't as strange as it looks, it's just that when something is doubled in D&D, it's increased by +100%. Each additional doubling also increases the base number by 100%.

So in your number above, you have the base number (100%), and each of the 4 doublings increases it by +100%, for a total of 500%.

It keeps criticals and such from getting completely out of hand.

Similarly, each Empower increases the base spell by +50%.

What about the case of 1.5? Is it 1.5+.75+.75+.75=3.75?

How did you get "adding half it's value to the first multiple" from "adding 1 less than its value to the first multiple"?

One less than 1.5 would be .5

So your equation would be 1.5+ .5+ .5+ .5= 3.0

Because that's the way it looks in 2+1+1+1. See what I mean? It was just kind of wierd in my head. Makes perfect sense now. Thanks a bunch, Cal! You're my hero!
